I did a search and found some similar stuff, but nothing exactly like this. When I try to build a city plan, random chunks of the city are missing. For instance, the deck on top of the workshop house in Sanctuary is gone, but the fence around it and furniture are still there. This is true of both RotC default plans as well as ones I've downloaded (or at least as far as I can tell). I thought it was Scrap Everything or a build limit mod so I deleted those, but still have the problem after starting a new game without them. Are there any other known mods that could be causing this? I play with quite a few. No Welcome to Goodneighbor, Conquest, or any of the other largely buggy ones I've seen mentioned before in similar posts.
