Resident Evil 4 Remake errors

Backstory
>Luis' grandfather died when bitten by a Plaga Colmillos... decades before the Plagas were unearthed.
>Luis worked for Umbrella in the division that created Nemesis... years after the development of Nemesis took place
>Ramon is cured of his disease by the Plagas... years before the Plagas were unearthed
>In the OG the only dominant Plaga was for Saddler, but here they add the Superior Species which is mass produced for every boss that transforms, which contradicts Damnation which says it's the first time someone managed to mass duplicate Plagas.
>The file that explains the creation of the Superior Species Plaga says they just got Ashley and are going to use it on her, so it would seem that all the bosses in the game had 1-2 days to learn how to use their virus? Especially if Ashley had to drink the liquid and be in a coma for several hours for the Plaga to develop, and they all had to do the same thing.
>Wesker is already commanding Tricell, so this timeline doesn't include the Rival Organization and creates continuity errors with RE1 and Umbrella Chronicles.
>Krauser never met Wesker and works for Saddler unironically, so it isn't explained how he found out about a secret cult in Spain or why he is angry with Leon if Operation Javier had Krauser as the sole survivor, i.e. Leon did not participate. That Krauser was the sole survivor and became a fugitive from the government also makes it unclear how he escaped from South America to begin with.
>The new Operation Javier didn't involve BOWs, which makes it impossible for the The Family in RE6 to get the Veronica Virus after Operation Javier.
>Krauser's motivations are that he wants to break the cycle of “soldiers being pawns”, and he does this by becoming a pawn of Saddler (in the Remake he has no plans to betray him) and by taking the Superior Species Plaga which according to files, causes scientists like Anabelle to remain intelligent but without a will of their own, with all their desires originating from what Saddler would want.
>Wesker already attempting to create Uroboros in the final cutscene creates a continuity error because he doesn't come up with the Uroboros plan until he finds Spencer, which is why the OG RE4 mentions Wesker and Krauser are working to create a new Umbrella PMC. If they aren't doing this in 2004, the appearance of Umbrella Blue and the Albert-01 gun in Resident Evil VII comes out of nowhere

Village
>The girl sacrificed in the opening cutscene is never identified and the reason for her sacrifice is never explained. The file Iluminados 4:3 speaks of a vague "judgement" given to outsiders, and there's also mention of regular animal sacrifices to keep the crops fruitful, but that only mentions animals. This gets no elaboration or clarification and ends up as unexplainable as the scene from the OG RE4 where Ganados attempt to sacrifice Ada (and that game had three weeks to be written). The addition of extra people who disappeared around the time of Ashley's kidnapping also raises the question of why local police didn't investigate the cases before Leon's arrival; also, it makes Leon look incompetent when he needs to be briefed about the extra disappearances on the intro's car ride, versus the OG which had Leon inform the police that the disappeared girl was the President's daughter back at the station or Darkside Chronicles where Leon was well aware that many girls had gone missing at the time of Operation Javier and took that into account when he descendend into South America.
>In RE4 OG, Leon learns of Ashley's wereabouts in Spain because Ada leaked the info to the government, as the Rival Organization had ordered her to betray Wesker. In the Remake, National Security finds Ashley on their own and Ada is surprised to bump into Leon, an implausible coincidence.
>In the OG, Leon is the sole agent sent into the field because the Government is trying to find who betrayed them from inside and kidnapped Ashley, but this gets no explanation one way or another in the "more realistic" Remake.
>The environmental storytelling in the intro walk to the Village makes no sense, as the road is blocked by a fallen tree and the only available path leads to an individual Villalobo house, which makes it impossible for the Ganado to have hired any outside help to carry out their complicated constructions in the game if a car couldn't make it to the village, and also makes it nonsensical that the Cop who stayed in the car could be taken to the Village and burned alive before Leon gets there.
>In the OG, Leon kills the first Ganado in self defense and then is distraught enough about the possibility that he killed a human being that he immediately briefs Hunnigan, a scene that also sells the deception of the Ganados. In the Remake, Leon walks through bloody barbs, walls filled with painted messages, and a cultist talisman, only to then find the first Ganado, who acts inhuman, has red eyes and disheveled hair, and doesn't acknowledge Leon's presence, defeating the point. Despite all these telltales signs, Leon seems none the wiser and when the Ganado gets closer he panics and breaks his neck from a kick without attempting to put distance between them or ordering him to freeze like in the OG, which makes Leon look incompetent, especially since he doesn't call Hunnigan afterwards.
>The opening house having a handy conspiracy board showing information about the kidnapping of Ashley makes no sense considering it belonged to a random Ganado, although more Ganados spawn in after killing the first one for some reason
>When you jump out of the house you cross a bridge with a blood trail, but it makes no sense because the only way to get to it is by jumping from a window and the Ganados dragging the cop to the Village Square wouldn't have done that
>Leon speaks Spanish when talking to the first Ganado. For everything else in the game, from Salazar or Saddler communicating with their men to the keycard computer's speakers, which should use Spanish, the game defaults to English.
>The Church Bell pacifying all the villagers is still as unexplained as the original game written in just three weeks
>When Leon finds Luis captured in a basement at the end of Chapter 1, there's no explanation for Mendez suddenly showing up down there. Leon then yells at him to stop, something he couldn't do to the shorter and less intimidating initial Ganado and which he's attempting after he's learned he can't reason with any of the villagers. There's also no justification for Mendez infecting Leon with the Plaga, an act that was originally carried out by Saddler in the OG and Mendez couldn't understand. In the OG, Saddler hid Luis and Leon together to draw out Ada. It also makes Mendez's attack on Leon in Mendez's house nonsensical in the Remake, since he'd already know Leon shares their blood.
>Leon begins seeing visions of Saddler minutes after being injected by the Plagas while unconscious. However, the Foreman's Log shows Plagas' infections require at least a week before psychological signs begin showing up.
>The Remake removes Luis' backstory/cover story of being a police officer, which helped explain why he'd start working for Los Iluminados since he felt heroes were unappreciated and acted as a foil to Leon's efforts as an officer in the OG RE2 were reduced to nothing when Raccoon City was destroyed. This is replaced by nothing in terms of Luis's motivations, with him joining Umbrella for some reason, quitting for some reason, and then going back to Villalobos and helping The Iluminados develop BOWs for some reason even though the Iluminados were responsible for killing his grandfather and casting him out. How he even managed to survive at five-years-old, go overseas and afford college goes unexplained as well.
>Luis calls Leon a "quiet guy" unprompted, even though Remake Leon can't keep his mouth quiet for two minutes in the Remake, even when he's only speaking to himself
>Leon hears Mendez's footsteps before Mendez appears in front of him at his house, yet when he ambushes Ada at the same location his approaching makes no footstep sounds.
>Ada rescues Leon from Mendez's chokehold by shooting at him through a window and then leaving. Since she doesn't wait for Mendez to jump after her like in the OG, there's no justifiable reason for Mendez to leave Leon in the floor instead of finishing the job. Ada's shots not making Mendez flinch also established he was an uncommon and intimidating Plaga specimen, but in the Remake every single regular enemy takes five shots without flinching.
>The files regarding El Gigante simultaneously state he was born 17 months before Leon's arrival, but also depict Gigantes being worshipped in ancient Iluminados religious texts. If these files even refer to the same El Gigante, it's not explained why the first one you encounter is of particular religious importance and not any of the Gigantes in the Castle or the one Ada fights in Separate Ways. Also, they state it grew into a giant since it was a baby, contradicting lore from media released after RE4 OG such as Incubation, where it's stated that babies cannot survive being infected by Las Plagas.
>The Cabin sequence ends when Ashley opens the upstairs door after ~10 minutes, despite the fact that outside of the Cabin you can see a simple ladder that she could have climbed in seconds. For that matter, the trio could have left from the hole that's covered by a shelf that they use to let Ashley out at the very beginning
>Luis reveals he extracted his Plaga by showing a chest scar, despite the special radiation device leaving no scars in Leon or Ashley, or even damaging their clothes
>Hunnigan justifies taking refuge in the Castle because the rain is too intense for a rescue chopper to come close - despite the fact that rescue choppers fly while it rains in the real world, and the RE4 Remake shows little more than a light rain shower. In the OG, the chopper was taken down by Los Iluminados.
>Mendez gets to his final boss location before Leon, despite Leon being ahead of Mendez. The location of the fight also has no lore or stated purpose, versus the OG where a file explains it was used to enlighten betrayers.

Castle
>Luis calls you when you first arrive to the castle, and the little screen showing his face shows fountains of black liquid behind him. When we see the conversation again from his perspective in Separate Ways, he's inside a tower with no black liquid anywhere near.
>The first time we see a Plaga Type Mandibula occurs when a cultist kills himself to trigger his transformation. This effective method is never used again, the transformations depending on random Leon damage or the Lantern Ganados triggering them
>Ada infiltrates the Castle to rescue Luis by disguising herself as a religious Ganado, even though Saddler can see through the eyes of his Ganado and could notice that he can't see through Ada. We know Saddler can see through his Ganado because he alerted everyone to capture Leon and Ashley the second they left her cell in the Church.
>Upon first meeting Leon, Ramon sends regular Ganados to kill him instead of the Verdugo and U-3. In the OG, this was explained by him saying "the time for games is over" when he sends Verdugo after Leon, meaning he was playing with his food. In the Remake, it's unexplainable since he sends U-3 against Ada in the first fight of Separate Ways.
>The Garradores need to be chained in order to be controlled, even though the Remake established that El Gigante is pacified with an incantation from the Ganados with lanterns which would also apply to Garradores. The same applies to the Regeneradores, especially when one escaping during their development resulted in 20 dead.
>Why does the red lanterns trigger the ganados's Plagas but not Leon's or Ashley's?
>Leon isn't surprised to see Ada is still alive, despite the fact that he doesn't get to see who throws the rocket launcher at him in 2 Remake nor when Ada shoots at Mendez through the window.
>Why does Ada tell Leon to forget about Ashley if he wants to survive and get a proper greeting if she tells Wesker Leon is being useful as a distraction?
>When Leon gets trapped inside a cage, a group of Ganados flood the room. Later, when Ashley makes her way to the top floor, the key to the room turns out to be in the pocket of the Ganado upstairs, so how did the group of Ganados get in downstairs?
>In the Ashley chapter, she can freeze Armaduras by casting the blue light at them, despite the fact that during Leon's fight in the Armaduras's room they only froze upon touching the flame, regardless of how close they were to its light.
>If the Armaduras are part of Saddler's hivemind, why are they trying to kill Ashley instead of capture her?
>After escaping from the Armaduras, Ashley is captured by Ganados because she wastes time trying to jump off her ledge to be caught by Leon. When you played as Leon in the previous Chapter, you could clearly see a ladder on the side of the ledge.
>When Leon shoots the Verdugo while he's taking away Ashley, it makes him bleed. When you shoot him during his boss fight, he doesn't bleed.
>U-3 had to be infected since she was a baby in her mother's womb for the insects to hatch successfully. Seeing U3's success, the Verdugo proceeded to infect himself, an adult, successfully.
>How is U3 so powerful and can extend her limbs and tentacles like Saddler if she doesn't have the Dominant Species Plaga?
>How did Ada call Leon when she was Ashley being taken by the Verdugo if she never got Leon's frequency? Why doesn't Leon ask her how she hacked his line?
>Ramon sends the Verdugo to kill Leon even though in the remake Leon doesn't shoot Ramon's speaker so he has no way of knowing that Leon survived the fall or a reason to think so.
>Luis tells Leon that they have to use the dynamite to reveal the path he used to infiltrate the Castle. When you use the dynamite, the only thing the path leads to is a small hatch that leads to the lava room with the two Gigantes. Where is Luis's access?
>When Ashley is mind-controlled by Saddler and stabs Leon, she backs away until a trap separates her from Leon. When the cutscene ends Leon magically retrieves his knife even though Ashley threw it away on her side of the trap.
>There are 38 Novistadores in the castle's Dance Hall, but only a couple in the Novistadores' nest.
>Garradores can't hear if you do knife executions on regular Ganados, but they hear if you knife the air for some reason. They also ignore the sounds made by Ganados and know not to attack them, for some reason.
>Luis walks with Leon for many hours, tells him nothing about the radiation treatment to remove the Plagas, then one moment before he dies he sends the radiation treatment file to Ada to send to Leon?
>Why is Krauser the only Ganado to have gained super-speed?
>Ramon transforms into his boss form after receiving the trauma of three pistol shots. Mendez doesn't transform until his final fight despite having two cutscenes where Leon shoots him several times and a whole gameplay section where you can shoot him as much as you want.
>The chalice used to feed Ashley the black liquid is the same asset as Berengario's Chalice in Resident Evil Village, creating a connection that the writers refused to acknowledge or develop
>Since Ramon never merges with the Verdugo in the Remake, it's never explained what he turns into or where he falls into that has black tentacles that look like the Megamycete. It also renders Glenn Arias merging with his bodyguard at the end of Vendetta unexplained. The ridiculous amount of mass gained by Ramon also violates the Hayflick limit established in Resident Evil VII.


Island
>When Leon finds Ashley sleeping on the Island he injects her with a proper Suppressor that Luis put together with all the ingredients and several hours, and it takes several hours to take effect until Ashley wakes up. Ada uses a Suppressor made in half a minute by Luis leaning against the castle wall with spare ingredients and is cured in a couple of seconds.
>In the OG Saddler asked Luis to create a way to extract the Plagas in case an important scientist was accidentally infected and they needed them to become intelligent again, but in the Remake there's no explanation why there's a special radiation device that extracts the virus and Saddler allows it. The file about the special radiation device also says that the operation would kill someone who attempts to extract a fully matured virus, which doesn't happen to Leon nor Ashley.
>Saddler preaches that all of his hosts are the "Holy Body" he worships and speaks for; he also says this while pointing at the Amber. Later, a file from Luis states the Amber could be more powerful than Saddler's power, implying that it's the real object of worship of The Iluminados, and something separate from Las Plagas, or perhaps a new species of Plaga. This confusion is never clarified.
>After Ada is kidnapped by Saddler, Ashley asks where she went, despite the fact that she was unconscious when Ada was arround. Leon responds that Ada isn't the type to roll over easily, despite Ada falling to the garbage disposal and waiting for Leon to rescue her in RE2 Remake, and then asking him to complete her mission for her.
>Krauser tells Leon that the fortress for their final confrontation is perfect because the place has seen the “blood of generations” even though the island is the refuge to which the Iluminados went to escape persecution by the first Salazar Counts and be safe.
>When Leon and Ashley arrive at the Amber repository in the Island, Saddler controls Ashley and tries to get her to shoot Leon. When Ashley resists, she and Saddler leave, leaving Leon alive for no reason, while removing the OG's explanation that Saddler wants Leon as his bodyguard. Saddler later spares Leon's life for a second time when he commands Novistadors to take down Mike, stares at Leon, then walks away.
>Ashley's arc makes no sense: She's terrified -> She has her chapter where you play as her and says she's going to rescue Leon, but fails and is kidnapped -> Leon tries to rescue her from Ramon but fails, he's thrown down the hole and Ashley is forced to drink the black liquid that knocks her out -> Leon finds her on the island half a day later and heals her -> She wakes up and learns that Luis died -> Now she is cheerful, independent and makes jokes about being the Master of Unlocking?
>The location of the Novidastores's nest makes the presence of Novistadores in the Island unexplainable. Furthermore, the Amber repository is on the Island, even though it the Plagas are unearthed below the Castle. Finally, the Island's ritual room includes a Monolith with an inscription saying the Plagas are below the writer in the Castle, even though the Monolith is placed miles away.
>Luis contacted Ada because he believed if she and Wesker got their hands on the Amber, it would be the only weapon capable of defeating Saddler. However, Wesker simply orders a red rocket launcher and Leon uses it to kill Saddler, leaving the initial thrust of the story nonsensical
>The remake claims that the Ganados lose the cognitive functions to do complex tasks, but there is an entire mining operation that uses explosives and a minecart track, and on the Island they use computers and monitor security cameras.
>Saddler controls the Novistatores in the final fight, even though they are the fruit of combining humans + black liquid + insects, without using Plagas. The black liquid is never addressed by characters or explained.
>How can the final boat ride be supposed to be Leon retracing Ada's path to enter the Island if Leon keeps doing sudden drops that would be impossible for Ada to have climbed upward?

Separate Ways
>Why do the ghost Pesantas's swings degrade Ada's knife durability if they aren't real?
>Ada contacts Luis after finding his secret code on his pack of cigarettes. Only why didn't the Ganados take his radio away when he was captured with Leon?
>How does Ada continue communicating with Wesker after the communications are jammed?
>When Ada returns to the Village, there's messages written in paint. Why do the Ganados need to write stuff down if they have a hivemind?
>When Ada sees the Gigante's Plaga, she says "What the hell is that?" Considering El Gigante is Villalobo's oldest BOW, why wouldn't Luis have informed Ada and Wesker about it when he invited them to the country?
>Why did Luis meet Ada in the Village if he left the Ambar in the Castle? Why does he say "I didn't expect to come back here" when him and Ada return to the Castle if he left the Ambar there?
>When Ada fights the Garradors, they somehow ignore the sound of explosive arrows exploding and go towards her when she attacks with the crossbow.
>When Luis hands the Amber over to Ada, touching it causes Ada's Plaga to react and causes her to flinch. When Krauser picks up the Amber by himself, his Plaga shows no reaction.
>Before Ada fights Pesanta, she follows Luis through a huge set of broken ladders she has to traverse using her hook, so how did Luis make his way through?
>Ada makes Pesanta transform into her Boss appearance by launching a broken stair railing at her with her hook, something that doesn't make sense unless Ada has super strength. If she can launch a huge piece of metal that fast from that far away, she could pull any enemy towards her using the hook during normal gameplay.
>When Ada takes the elevator to Ramon's Throne Room, she sees Krauser landing on the building in front of her and then jumping down on his way to the room, but this is impossible since Krauser couldn't have taken the elevator Ada is occupying and examining the floor during gameplay shows there's nowhere Krauser could have jumped from and that he jumped towards an abyss.
