Experience bar error

[DuckDastardly]

Noticed I started getting this error right shortly after hitting 81 and only after I started to get a little rest xp. Not sure if you plan on fixing it, but thought I would report it anyways.
Just noticed I have another error that is exactly the same EXCEPT for the event. The event in that one is: event = "PLAYER_XP_UPDATE"
