I'm trying to complete "A New Order", but recuiting Gunmar is bugged, I got Brood Cavern, and the objective arrow is stuck at the back of the cave, it never updates or moves even after all of the bears are dead, Gunmar stays in combat mode and won't talk to me, I've tried entering the cave first, killing all of the bears, then talking to him, I've tried reverting to a previous save, I've tried using "Calm" on Gunmar to try and force him to put away his weapon and talk to me etc. Nothing works, I don't know what to do!
