      The bug

      When using a non-[a-z0-9/._-]-character as biome in a superflat preset, the game crashes.

      How to reproduce

      1. Open MC 1.14.4 or later
      2. Create new superflat world
      3. Choose a preset that uses a non-[a-z0-9/._-] character as biome (e.g. minecraft:air;*;)
      4. Click Done (or whatever button it was)
        → The game crashes instead of giving a proper error message

          [MC-164499] Game crashes when creating customized superflat world with unparsable biome

          You used a comma (,) instead of a semicolon (;) after minecarft:dark_forest, so the game is trying to parse all of minecraft:dark_forest,stronghold,biome_1,mansion,dungeon as the biome.
          Probably still a bug that the game crashes instead of giving a proper error message.
