Returning Block::AIR when chunk is not yet generated (CHUNK_STATE_GENERATED set to false) is also a way to avoid thread-unsafe concurrent
access to the IntervalMaps data structure, since CHUNK_STATE_GENERATED is set to false before
generating the Chunk and set again to true after generation is complete
