Pokémon R&B Known Bugs

Potentially gamebreaking bugs
- If a Pokémon uses Endure and is hit by a multi-hit attack, the game can softlock.
- Permanent Aurora Veil in Seafloor Cavern and Tailwind on Mt. Pyre Summit can sometimes softlock the game. Deactivating move animations solves the issue and usually restarting the game is enough. Save your game before engaging battles within these areas.

Double-battle related bugs
- "Left guy" bug: Double battles can start with the opponent's slots being reversed to what they should be. Only happens in double battles composed by two trainers. Saving and reloading right before a double-battle prevents the issue.
- AI doesn't recognize a partner Pokémon correctly as fainted in double-battles, meaning it can still be discouraged to use Earthquake even if it's the only Pokémon remaining on their side of the field.
- Custap Berry can activate mid turn in double-battles if the first attack gets the Pokémon into berry activation range.
- Spread moves in double-battles:
=> If the AI only has one Pokémon and it's in the left side of the field using a spread move it will deal the full single target damage to both of the Player's Pokémon.
=> If the AI only has one Pokémon and it's in the right side it will always take reduced damage from spread moves user by the player.
=> If the Player uses a spread move that KO's the right side AI Pokémon, the Pokémon in the left side, which immediately takes damage afterwards, takes full single target damage.
- Bringing in an Intimidate Pokémon in a double-battle from a pivot move (Flip Turn/U-turn/Volt Switch) causes Intimidate to trigger be at the end of the turn instead of immediately upon switch-in.

Ability related bugs
- Analytic bug: AI checks if the opposing Pokémon moved first on the previous turn. If the opposing Pokémon did, it calculates like Analytic is boosted, if the opposing Pokémon didn't, it doesn't. This also extends to Bolt Beak, Fishious Rend and Payback.
- Corrosion doesn't work on damaging moves with a poison chance against Poison-types.
- Disguise will break on indirect damage like Iron Barbs or Burn/Poison.
- Emergency Exit can trigger multiple times per fight.
- If Ice Face is broken by U-turn, the U-turn user does not switch out.
- Libero/Protean Pokémon will see the damage of all attacking moves as affected by the weather in the same way their current first-type does.
- Magic Guard Pokémon still take damage from Innards Out and Powder.
- Skill Link doesn't work properly against Weak Armor Pokémon.
- Shield Dust Pokémon can still be poisoned via contact moves used by a Poison Touch Pokémon.
- Trace in double battles has multiple bugs: https://discord.com/channels/843083719232847934/1086489733733040128/1128880956422500462

Move related bugs
- Brick Break and Psychic Fangs will remove barriers even when used against an immunity.
- Burn Up and Triple Axel will consume 2 PP per attack.
- If a Pokémon gets a kill with Burn Up it doesn't lose its Fire-type.
- Dragon Darts in double-battles doesn't avoid Fairy-types.
- Flare Blitz induced burns can happen at times they shouldn't, using Powder, Protect (and variants) against it can still get you burnt. Using Powder on a Flare Blitz still causes them to take recoil damage.
- Poltergeist hits Pokémon in semi-invulnerable states such as diving, flying, etc)
- Retaliate can deal double damage one turn after switch-in if a teammate has fainted via indirect damage, e.g. Poison/Burn.
- Rollout is seen as a move with 480 BP for switch-in-AI.
- Spirit Shackle will still trap Normal-types who are immunte to it and Pokémon using Protect (and variants).
- Wide Guard doesn't defend against Expanding Force.
- Wide / Quick Guard can fail upon consecutive uses like Protect.

Item related bugs
- Big Nugget Fling damage is 30 BP instead of 130 BP.
- Eject Pack can trigger even if the holder is the last Pokémon alive, send out an already fainted Pokémon, which will immediately faint again.
- An Electric/Grassy/Misty/Psychic Seed will not trigger immediately if the Pokémon holding it is brought in via a pivot move (Flip Turn/U-turn/Volt Switch).
- Focus Sash can activate multiple times if Future Sight is used beforehand.
- Gems only increase the first instance of damage, so e.g. the first hit of a multi-strike move or the first damage dealt on a spread move used in a double-battle.
- Life Orb damage is received when a Pokémon with Life Orb is switched in via Eject Pack/Red Card.
- If a pinch berry is triggered from residual damage it's boost will not be granted, even though the game text says it does and the berry is consumed.
- Protective Pads ignores Fluffy.
- Shell Bell doesn't restore the right amount of health when a multi-hit move is used.
- If a Pokémon uses Shell Smash while holding a White Herb, the White Herb triggers halfway through the move, negating the Defense drop but not the Special Defense drop.

Other
- Melmetal and Kecleon have the wrong weight.
- PP is only maxed for the first slot in all AI Pokémon.

- Bugs that are either inconsistent, unconfirmed or one-of instances of bug reports that could not be reproduced
=> Frisk can trigger Download for a second time.
=> A Future Sight hit may not activate Emergency Exit.
=> Powder in double-battles will only protect the player’s left slot (slot 1), the right slot still gets hit (slot 2), though the AI Pokémon will still take damage.
=> Flinging stat raising berries can increase a different stats then intended in double battles (observed in the Route 123 double-battle against Jonas & Fredrick, never reported happening against Virgil & Nate at Mossdeep Gym).
=> Death from entry-hazards damage sometimes does not end the turn immediately, allowing the opposing Pokémon to move after a switch happens.
=> Switcheroo/Trick can fail if the target has no item.
=> When a Pokémon is switched in via an Eject Pack while Stealth Rock's are up on the player's side, after switch-in, the AI Pokémon takes Stealth Rock damage instead.
=> In double-battles, Intimidate triggering Competitive or Defiant can result in other Pokémon gaining stat increases.

- Visual-only bugs:
=> Strange Stream and Fairy Lock are funny.
=> If a Pokémon holding a White Herb faints before using it's item, the White Herb message will be shown post-KO.
=> Mega evolution icons can linger on the screen.

-Issues regarding the pokedex/calc:
=> King's Rock, Nature's Madness, King's Shield will not get exported and are shown incorrectly in the calc.
=> Some abilities like Corviknight's Unnerve are not exported correctly to the calc.
=> Triple Kick damage is calculated incorrectly, it assumes 3 hits of 30BP each instead of 10BP+20BP+30BP.
=> Triple Axel damage is calculated wrongly per individual hit, but correct in its potential overall damage (constant damage vs. increasing damage per hit).
=> Eelektriks evolution level is wrong in the pokedex.
=> Zygardes ability on Drake is wrong in the calc.
=> Some moves have wrong accuracies written in the dex. Always check in-game to make sure.
