so today when I went to dungeon to kill him, get skeleton key, and tried to escape. but when I searched his body to get skeleton key, had no key whatsoever. I reloaded the same part three times. the same result. therefore, I can't get out of dungeon. skyrim has many little bugs. but this kind of thing is really bothered me because I can't complete mission at all. any solution for this? do i have to start this one again from scratch? I don't want it.
