Current Chunk for Entity and Block Entities, counts by entity type This enables us a fast reference to the entities current chunk instead of having to look it up by hashmap lookups. We also store counts by type to further enable other performance optimizations in later patches. 2018-07-04 09:55:24 +02:00			`From e684a193f95395b7881bd0d96a1961ac00aa40b9 Mon Sep 17 00:00:00 2001`
