got the same issue. After going to sleep the cutscene just doesnt trigger and dag is not there at all cant even find him on my ship.
theres no way theyre gonna fix this. I cant even interact with valka and go to asqard since i never got her quest. nice scam ubi
after building seer hut i never got the in dreams side quest that enables you to go to asgard .I am at settlement lvl5 and still cant get the quest or interact with valka at all.
