Crash, Custom Worlds
I am trying to update a world-gen datapack from 21w05a to 21w06a. In doing so I need to load said datapack into a new world. However, the game crashes as soon as the game starts generating chunks.
How to reproduce
- Create a new world
- Add this datapack during world creation
- Begin generating the world
- Observe crash
