I don't know if this has been posted before, i tried searching but nothing came up so:
Most of the time decapitating someones head doesn't kill them, and they move around with no head!
When doing bounties, trying to hire mercenarys like Milites, they have one to three lines of dialogue claiming that he is a wanted person, this happens when i did a bounty that is the Milite infantry, so i cant hire him and it ends up with me killing him in the tavern and him respawning.
When talking the my castle guards they say "Surrender or die, your choice" but nothing happens, i think the text has been misplaced.
