Repro Steps:
Unknown
But one would assume: play world content from the Marketplace Store.
Observed Results:
Players spawn in a void/flatworld after creating Marketplace world content.
Expected Results:
Players should not be presented with a void/flatworld world when creating Marketplace world content.
Screenshots / Videos attached: No
Notes:

• It's a void world because that's the default world generation when we generate the world files.
• Is there a check to prevent world corruption on world creation/download?
• We can provide the Player Feedback data; give us a Request on Compass.
