I noticed this when trying to generate a custom dimension that generates a ceiling at y=255 with overworld biomes.
The log was being spammed with errors like these:
Note how y is above the world limit.
In this particular case, when going to that location, it appears like a village tried to generate at this location.
Changing separation and spacing to 4095 and 4096 for villages seemed to solve the issue. I am not sure if other structures might be affected as well.
- Generate a world spawn with the following preset: overworld_ceiling_255-1.json
- /execute in buggy:game_breaking_experience run tp @s 752 256 -208
→ The game gets extremely laggy
