When I use Tectonic and Terralith together on Mohist, there is an issue with incorrect chunks being generated.

There were many large walls generated, and I know this is due to a conflict between terrain generators. It only returned to normal after I removed Tectonic and deleted the chunks to regenerate them. However, according to the mod descriptions, the versions of Tectonic and Terralith are supposed to be compatible with each other. I’m not sure whose issue this is, so I’ve raised an issue on both sides.

You didn't like, install one start the world and then install the other right? I can understand terrain gen being off but what you see there is like, two completely different biomes and climate regions, which is pretty wild, I haven't seen anything like it before, I installed both together and I've traveled pretty far in them and haven't seen that, I'm on 1.20.1
