I recently installed the Hearthfire dlc (bought from steam) and I have about 80% of my Lakeview manor house built. I dont crash anywhere else in the world and I also dont crash in the first room of lakeview manor. But, when I enter the second room (main hall), the timer starts ticking. In roughly 10 seconds my game CTD's (crash to desktop). I have no idea why, I have ruled out the mods by uninstalling them 1 by 1 and trying over 50 combinations of them together and it still is yet to go away.
I might just play without it since I see that after disabling it the saves when hearthfire was installed still remain in the folder.
