You'll never believe this. I was playing my Argonian light swordsman and I was in Markarth. I was talking to Degaine about stealing the statue of dibella, and suddenly, a dragon attacked. I didn't want Degaine to die because I needed the quest for money (which I was out of) so I left the city.
This technically counted as Skyrim in the game engine, so wouldn't you know it, about 5 or 6 forsworn showed up and the dragon ,so convieniently, didn't leave. And to top it all off, I accidentally slashed one of the guards in the fight and then EVERY NPC was out to get me. The fight was so long that it autosaved so even though I died like 17 times, I had to keep fighting, and I couldn't load one of my previous saves because I was doing a nine-hour gaming binge and hadn't properly saved since Sovngarde.
Not a good day.
