Hello, i sometimes have this error in console when player joins.

ItemJoin version 4.5

Thanks for the report! This bug has been fixed and will be available once ItemJoin v4.6 is released.

Thanks! Plugin works fine, just that keeps spamming my console. (I have already deleted it with ChatControl)

Fixed as of ItemJoin v4.6 and it has been released!
