Re: Soldier's Peak - Bug?
Small correction to elrofrost's solution: "make jump to" > "soldier's keep (repaired)". Otherwise, major kudos for finding the solution. I was ready to chuck it myself. I also had the problem (still do) of Sophia's invisible armor which is likely due to the "Grey Wardens of Ferelden" mod I installed. I can't help but think it caused this Avernus problem as well since I've never had this issue in previous run-throughs.
