The Whiterun Halls of the Dead kills my save file!
Here's a strange thing. I decided to take a look around the Halls of the Dead in Whiterun for the first time. After coming back out I suddenly get a huge FPS drop, and I find that no saves - auto or if I make them myself - will work except the one I made just before I went in.
I'm using some of the 2K texture packs; could it be them? Any ideas?
