If I wait a few hours in real time, or a day perhaps, it will fix some of the crashes I am having. Like currently, it keeps crashing in Shivering Isles where I'm trying to do the restore the cold flame quest. I tried loading a previous save, and now that save crashes, and it crashes instantly unlike the newest save. I didn't have any problems with the previous save before, and now out of the blue, it starts crashing when I load it up.
