#roofing bug

I’ve been trying to build a house and the roofing works fine but when I try to place a roof in this outdoor room the ceiling keeps disappearing if I get too close (even though it says it’s there) and the roof just won’t recognize the second floor - it keeps placing on the floor! 😭 😭 😭 This happens with every outdoor room I have. Only the main house allows roofs! I’ve tried, bulldozing the lot and replacing it. Deleting the rooms and making new ones. Flattening the terrain. Has anyone seen this? 🙏 🙏 🙏
