Landmark creates huge terrain hill in pass

Issue: after placing a landmark it changed the land making a steep hill on the pathway.

Description: on placing a landmark near the border of a region close to where i have a path and a pass. a large steep hill was created. People seemed to have no issue getting past this though.

This was sort of “fixed” ages back when I stopped trying to flatten the terrain under buildings. But I probably do need to go back to doing that. The issue here is the landmark trying to flatten the ground underneath itself, and that fighting against how the mountain pass was trying to deform the terrain in a different way around itself.

So this isn’t really an issue right now, but probably will become an issue again at some point; I need a better priority system for applying these terrain adjustments, I guess.
