When using a custom biome, custom feature, or custom carver and using it in a buffet world the game starts spamming the debug log with Invalid biome data received, starting from 0: -1, -1, etc.
The game started getting laggy and would probably get unplayable.
Steps to reproduce
1. Download provided data pack or any data pack that uses custom biomes.
2. Add data pack to a world and create a world that is a single plains biome world or is a custom biome/ uses custom settings.
3. Watch the error log and notice that the biome is ocean instead of plains or whatever the custom biome is.
