Issues Found:

LeadersBoards/Stats: I just noticed that the /stats and the leaderboards shows the players current stat. I meant for them to show their highest killstreak ever gotten and just keep it as that. If you could add/edit, that would be amazing. I think that's just something I didn't say properly when I requested the plugins.

Kills: I'm still having that issue where I get a kill and it displays it as [0] for their first kill and [1] for their second kill.
Every other bug was fixed, thanks <3.

Portal: This is more of an addon if possible to messages, I wan't it to say " (!) You have been teleported to the arena!" when they enter the portal.

Leaderboards Monthly: In the original I wanted there to be a monthly sign so monthly highest kills and monthly highest kill streak.
If possible have a command /lb monthly reset or something along those lines. ( not sure if this is considered more work or if it's simple) if it's way more work let me know on the price to add this.
