contains the errors that need to be fixed.

Currently there are no errors. Everything is working.

Contains 1 old warning message about HostageArena.onSpawn() needing
@ArenaEventHandler(needsPlayer=false)
or
@ArenaEventHandler(entityMethod="getEntity")

Needed for events that have more than one entity method, like the Arrow
Event.

This particular issue was fixed with
@ArenaEventHandler (needsPlayer=false)
