Yeah, I always rebuild my bashed patch whenever I un/install something. I can walk through the floating buildings. I have a backup of my Oblivion folder from a stable modded install. I'm just going to load that up, and see if that fixes things. If not it's probably the save files themselves, in which case, after 80 hours, I'll probably just say "eff it" and start on Skyrim. :yes: Edit - Well, even after a fresh install with no mods installed (other than my demon skin) I'm still getting the invisible castle and floating buildings in Skingrad. The problem has got to be in the save file somewhere. So sad...
