@ubi-mark All files successfully verified with no repair necessary. I backed up to an earlier save and continued the game out of Asgard. I will return and try again later this weekend and see what happens.
I beat Fenir, the graphics were glitchy but I finished the quest, but when I walk over to talk to Tyr, he just stands up then sits down over and over again. The cut scene doesn't start and I can't move.
