I've been having a lot of fun with settlement building with my current character. I've built a major structure, and torn it down twice, and I'm considering doing it again. The thing is though, that no matter what I do, there are two houses that I can't scrap that screw things up entirely. I suppose those houses were made immune to scrapping because the devs were afraid the game would be unbalanced if we could just clear the areas we wanted to...
Anyway, has anybody tried "mark for delete" on one of those houses? If so, is there a concrete base under it, or is there a graphics hole in the ground at that point?
