But now after a quest I had problem that seemed to disappear but I couldn't understand it. After the Desolate Mine quest whenever I tried to fast travel to the Imperial City I got a CTD, no matter the place I wanted to enter from. But after I traveled with my horse until the city and entered it the problem disappeared it seems completely, and I am confused.
Can you please explain if you know why did this happen and why it corrected itself like this?
