I did the quest ''denounce a lord to his face", but when I tried to duel him I got in the middle of a plain land with a small arena on the distance, there was no way to get into the arena, and I figured out my adversary was in the arena.
There were "leave area" things all around the place, I tried to leave to see if it fixed, but it got into an infinite loop with him chalenging me and my character saying "I'm not afraid of you" and it shows a glitch screen, then I click in the only option (I don't remember what it said) and it goes back to him chalenging me and so on
