Hello,
Structures from the mod sometimes spawn near mountains and cuts through it like there was no structure_void block in the NBT to avoid that.

I'm playing on The_Graveyard_2.1_(FORGE)_for_1.16.4-1.16.5
Forge 36.2.23
Minecraft 1.16.5

Your mod is amazing btw

Happens with 1.18.2 for the The_Graveyard_1.9.7_(FORGE)_for_1.18.2.jar version.
