Subject: [PATCH] Allow removal/addition of entities to entity ticklist during
tick
It really doesn't make any sense that we would iterate over removed
entities during tick. Sure - tick entity checks removed, but
does it check if the entity is in an entity ticking chunk?
No it doesn't. So, allowing removal while iteration
ENSURES only entities MARKED TO TICK are ticked.
