Hey can you try cleaning up the Redirectors in the Procedural Nature Pack folder and see if that fixes the issue? Here is a picture of what I mean.
- Right click on the main folder “Procedural Nature Pack” and select “Fix Up Redirectors In Folder”
- Then it should take a moment and ask if you want to Delete a few things and go ahead and click “Delete” at the bottom. Then try cooking again and see if that fixes it? Thanks!
