I think it is a very bad idea for people to dress up like cumans and hang out in a town where cumans raided, burned, and killed my parents. Standing not more than 20 feet from their graves. They wanted to fist fight as part of the Punch Me quest line. I saved first and tried fighting them, but to make their situation worse, they try to cheat you.
I decided to kill all of them. Is this going to break the quest? Even though they are all dead, the quest marker is still there.
