My house has lost it's "solidness", I can walk through walls and fall through the floor, though other objects like carpets are solid. I rezzed a copy of the same house from inventory, and I have the same problem, though I rezzed a different structure (a skybox) and that one is solid, so the problem isn't with the lot or my avi. Why should the copy, which wasn't rezzed when I had the problem, also be affected? I don't know what I did to cause this. Any ideas? Thanks.
