Subject: [PATCH] Avoid Chunk Lookups for Entity/TileEntity Current Chunk
SPECIAL 1.14.1 NOTE:
This patch caused a memory leak since the tile entity's chunk was set to null
before it was removed. Ensure this issue is resolved!
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.
