Long story short: I try to give Oengul (At Windhelm) the sword, and he says he will teach me blacksmithing and nothing happens... he doesnt take the sword, and no dialog box comes up.
The problem is that from that moment on, i can't activate things in-game. Can't rotate the pillars to solve puzzles, can't harvest blood, can't do a whole bunch of things so i'm officially stuck mid-game because of this bug.
How can i fix this? The nearest manual saved game is 10 levels below my current status, and i dont have time to re-play the whole game.
Thanks!
