Yeah so I was going back to Asgard to defeat Fenrir, When I get to the fight Fenrir just starts spinning in a circle, with that underground move he has. When I tried to run into his attack it just stopped him and he started going crazy. Also I hate that I have to travel 700m everytime I want to retry the quest. You could've just enabled the saving option, so I can save when I get to the island. This has surely been my worst experience with this game since I got it. It's game breaking and It makes me not want to play the game more since it's the only active quest that I have.
