The cow is stuck is asgard and will not move even if you break all the obstacles. the rock you have to move is stuck against a wall and even though the gap is way larger then the cow it wont pass through. This is causing me to not complete the last quest in Asgard.
Also the flyting npc in stavanger is not there. It has been missing since my first time in that city and that is also causing me to not get 100% in that area.
Mouths do not move during some Cut scenes but this is not game breaking like the quest issues.
