There was a problem hiding this comment.
Any specific reason on using a List instead of an array?

Overview
Description
BiomeMask and biome access generally are rather slow, and a lot of the slowness is caused by inefficient translation and slow contains checks. The adaption from NMS biomes to WE BiomeType can be simplified as we already set the legacy id (= NMS-internal id). The HashSet can be replaced by a boolean array, similar to how BlockMask works.
