[neoforge 1.21.1]Hills don't generate properly

[jinkhya]

Describe the bug
When you go to twilight forest the hills don't really exist (I'll add a screenshot)

To Reproduce
Steps to reproduce the behavior:

1. make an instance with just C2ME and twilightforest
2. go to twilight forest
3. run /locate structure twilightforest:large_hollow_hill for example to go to a large hill (but it's the same for all the hills)
4. you'll see it only has some remaining blocks and not actually a hill

Expected behavior

Hills to be normal
