Buildings can sometimes cut into the terrain. Is it possible to avoid this by making it look more natural, similar to how villages do it?

This should be fixed for the next update (not 100% sure).

Normaly, it's fixed in the last update for version 1.16.1. This will also be ported for old versions.
