@mcabree that's a shame

I managed to fix the issue which persisted even after building Valka's hut, by fast traveling to Norway and back again.
This time it played through until the end.

BTW don't do the next Valka part by drinking the potion to start "in a dream" until suggested power 90.

I have the same issue so I went back to a previous save and ignored the quest, but now whenever I reload the game it defaults to a wise friend and Eivor staggers and the screen goes all blurry like when he's drunk until I change the quest to something else.
It's getting to be a real pain in the behind
