Bug Severity

Major

What happened?

I created a new world using the "dimension stack" feature from immersive portals with the following dimensions:

Skylands 1
Void
Overworld
Nether

Upon starting generation for the new world, the game simply crashes. This crash only happens if BYG is running.
These are the only mods I have running:

BYG
Immersive portals
Fabric API
TerraBlender
Cloth Config v6

Did you isolate BYG?

I tried BYG alone

Could be related to the issue with datapacks mentioned here in #801 : #801 (comment)

This should no longer be an issue, if you still get this crash please comment/reopen this issue. Ensure you're using the latest versions of all mods relating to world generation and Terrablender!
