Hello,
Sorry for my English I am French.
I installed Terralith V2.2.1a in data pack (FORGE). On a Minecraft 1.18.2 server and I'm not using any other data pack.
After generating the world as indicated: start the server -> stop it -> put the data pack -> delete the region folder -> Restart -> play.
I noticed that there was a lot of vanilla generation (as pictured). It's normal ? Can we generate a 100% Terralith world.
Thank you so much for your help !!
Have a great day/evening!
