When entering any old world on any platform. Only the last rendered chunks will load. (Version 1.16.221 Only) The world can still interact with blocks and objects, but will not load any other chunks. Increasing chunk render distance does not fix issue. Restarting devices does not work either. It only affects Old Worlds started before 1.16.221. Any old worlds started in 1.16.221 will load normally. Tried on multiple platforms all yeild the same results.
