Subject: [PATCH] Avoid Chunk Lookups for Entity/TileEntity Current Chunk
In many places where we simply want the current chunk the entity
is in, instead of doing a hashmap lookup for it, we now have access
to the object directly on the Entity/TileEntity object we can directly grab.
Use that local value instead to reduce lookups in many hot places.
