Tried to do this. First thing I tried to do was fight a summoner, like the quest says. Spar with them, beat them to near death and move on. Problem is when they reset, the game seems to forget that I just beat them and treats it like I lost. Maybe it was just that NPC that was bugged. So I try the other summoner punching bag. Same problem.
So then I thought maybe it was just the summoner division that had this problem and tried to do a different division. Tried again with sorcerer, and the thing still reset without crediting me! The quest can't progress because the NPCs reset without adding to my quest objectives. And to make matters worse, guard NPCs walk in the way of my sparring with the NPCs. One hit in the wrong direction and suddenly I'm a fugitive. Is this a recent problem or has this been ongoing for a while?
