I tried to create a flat singleplayer world as my client crashed.
How to reproduce:
Singleplayer
Create New World
More World Options
World Type -> Superflat
Customize
Presets
(The Void)
Type into the preset field: minecraft:yellow_terracotta; (the block does not matter)
Click on use Preset
Done -> The game crashes
This crash is caused by the missing biome in the preset string! The game should just default the biome to plains and not throw an IllegalStateException (see crash.txt).
