Describe the bug
Upon clicking the "Create New World" button using any Planet Earth preset will continue to the loading screen, but quickly crashes the game.

To Reproduce
Describe the steps it takes to reproduce the bug

1. Click on Create New World in the world menu.
2. Set the World Type to Planet Earth.
3. (Optional) Click on Customize and pick any preset (does not matter, all of them crash).
4. (Optional) Close out of the Customize menu and click on Cubic Chunks. For some reason, you have to click Default three times to return back to No? I did not set it to No, and left it as one of the "three" Default options.
5. Click on Done and click on Create New World.

Expected behavior
I expected that the world actually gets generated and the player is spawned.

• What version of the BTE Modpack or Server pack are you running? (If applicable)
  No mod packs. I am using four extra mods but I highly doubt they are causing issues.
