Changing the world height introduces issues with chunk rendering. It's correlated with movement; once unloaded they don't try to rerender. This world has a 64x64 area centered at 0,0. World goes from 511 to -512

Spawning then hitting a mob when the chunks are unrendered causes them to stay permadamaged and move their legs quickly.

Does this count as a separate issue?
Did you open a backed up world if yes this might be a chunk border and the world may be corrupted.
Thanks.
This doesn't seem to be just a rendering issue: The chunks flat-out just don't seem to load once they have a block on them.
This is quite bad.
More notes on breakage:
A world of size 512 doesn't break, even if it stretches down to -128. This means that the problem isn't with negative coordinates per se.
I tried relogging but it just made the entire world not want to render anything.
