I cannot drink the potion to return to Asgard and whenever I try to leave the hut the camera zooms out and then a border stop me from travelling more than like 30 metres away. I cannot use the atlas as well. I have completed the main story I belive (pacified everywhere) but cannot work this out. Suggestions would be appreciated!
Hey @ahollyer07 and welcome to the forums!
Sorry to hear about your issues with the quest. As I understand you are unable to progress the objective that says "Drink the potion to return to Asgard"? We've received some reports of other players facing a similar issue and are currently investigating this.
Could you please provide us with a link to a short video showing this issue, so that I could confirm if it's the same problem? Thanks!
