World generation
When a buffet world's biome_source/type tag is set to minecraft:vanilla_layered, the game ignores the contents of the biome_source/options/biomes tag and generates the world with all DEFAULT world type biomes. This is especially visible in the latest snapshot if the biome_source/options/biomes tag only has nether biomes.
How to reproduce:
- Create a buffet world.
- Exit the world.
- Open the world's level.dat file and change biome_source/type to minecraft:vanilla_layered.
- Add nether and/or end biomes to biome_source/options/biomes and delete all overworld biomes.
- Delete the region folder.
- Enter the world.
What I expected to happen was:
The world would use the biome options to create a world that looks like default but with the biomes I had set.
What actually happened was:
The world ignored the biome options and generated a world with all default overworld biomes.
