Initial "clean-up" in addition to attempted fixes on:
Malganis should now be selectable after being defeated.
Arthas won't have opportunities to spam his devotion aura anymore
Arthas (shouldn't?) disappear if you move too far away from him. (Thanks for the idea ProjectOneCore)
ActII will no longer be able to be started via arthas' gossip menu
The crate event handler should be functioning perfectly now
The appropriate amount and type of adds should spawn on each new wave
