I have purchased land that needs more space at the ban line to build a (brick wall).
The front of my parcel is where the ban line is, to auto return the brick wall I desire to build.
It is apparent that terraforming the land to make space at the ban line, so the wall won't auto-return & stay in place is the next thing to do.
Messages say I don't have permission to do terraforming my purchased land, when I try to (edit terrain).
Who & where grants permission to do terraforming land?
