TeamErrorFix
A mod to fix the player either on another team or not on any team error
About this Mod
Fix for an error that is happening whenever there is a team change.
Made the mod because I had issues in replay mod and the server I play at have AFK system and whenever there is a team change the replay mod crashed at that point.
Example title of the error:
java.lang.IllegalStateException: Player is either on another team or not on any team. Cannot remove from team 'AFK'.
I saw a mod for 1.20.4 but not for newer versions. The mod: https://modrinth.com/mod/cannot-remove-from-team-workaround
