      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:

      1. Create a buffet world.
      2. Exit the world.
      3. Open the world's level.dat file and change biome_source/type to minecraft:vanilla_layered.
      4. Add nether and/or end biomes to biome_source/options/biomes and delete all overworld biomes.
      5. Delete the region folder.
      6. 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.
