Everyone:
I just finished the Civil War story arc and now I seem to have Hadvar attached to me as a permanent follower. There's no command to tell him to go home or whatever. I tried killing him, but that's impossible. I waited 24 hours in-game time to see if he would leave, but he hasn't. What the [censored] is going on?! Jesus, it's always something borked with this damnable game.
