Trying to generate something below y=0 results in game crash

Resolved
Fixed
4

When we try to generate something other than block layer below y=0, the game will crash with following informations (removed note about crash log generation, crash log itself added to the files)

 

As of 21w05a it seems to be fixed. Probably due to the fix of MC-212422, however the bedrock layer is still generated at y=0, so don't really have a way to tell.
