I have 4 outstanding Mysteries in the Rygjaflyke that are not receiving completion even though all tasks are complete:
The one with the man who tries to hunt wolves and dies (he is lying here dead)The one with jumping off the waterfall and recovering the item for lady (when i try to speak to her it gives me one chance to select Y and then goes blank.The battle against the ancient warrior near the top of the mountain. He is dead and confirmed but the icon still appears.And The Fly Agaric in Rygjaflyke with the 3 gates of Thor, Odin, and Frya. I complete this and nothing happens.
I have completed all other wealths, mysteries and artifacts in the game hoping this would get patched but I have not seen anything. I cannot back to an old save state as I am already complete with the game and did these near the beginning of the game initially.
