So since yesterday my game has started to crash when ever I get near Windhelm, just a little north of Kynsegroove seems to be the limit. I suspect it has something to do with my progression in the Civil War Quest, as I had just finished taking back the second or third fort after you take Whiterun when it started to act up, and it worked just fine before that. Personally, I think it has to do with a mod changing a reference somewhere, but I don't know how to verify this, or what to even do about it. Any help would be great.
