I've searched around the internet for a solution to this for a while, but can't find an answer. Apparently numerous people say this is likely caused by Deadly Dragons, but since I've never used that mod, that can't be my problem.
Basically, trying to do the civil war for the Imperials and just finished the Battle of Whiterun. I'm supposed to retake the Pale, as usual, but every time I get near it, the game CTDs. I've never had this happen before, and the only mods I've downloaded recently were the newest versions of the Unofficial Patches (Skyrim, Dawnguard and Dragonborn). Would one of them be causing this by accident?
