I had the quest disappear as well. I did all the wealth and prayed at the alter and then the quest was no longer on the map. I have walked everywhere I can around the Well of Mimir but nothing happens. I have watched videos on youtube that shows I should be in the water but loki is not there. I can go inside the well and no one is there to advance the quests. This is a major game breaking bug

I am having the same problem Loki is not showing up and the last manual save prior to this was 3 hours of me getting all mysteries and loot I really don't want all that time to be wasted just because of some bug. what is something we can do to fix this? @Ubisoft
