I just found out the hard way that the Redoran Kinhouse in Balmora gets locked up tight after doing the main quest for the town. That was one of my favorite buildings to pillage!! I've had Morrowind for a while, but I just kept putting off that particular quest, I don't even really know why, but now I kind of wish I hadn't done it. Maybe the devs thought it wasn't fair that one could go in and steal with no worries of getting a bounty?, Idk, but I'm sure going to miss stealing everything that wasn't nailed down in there.
