@ubi-wheelyduck Hey, I just went back to Asgard to get the footage but it all worked normally this time, Loki and the rest were back and the fight triggered when I brought the paint again, so all is good. No idea why it didn't work on my last visit or what fixed but it works now.

I left the area to wake up before finishing the boss fight, then I didn't play the game for a month until I got the new GPU and started again recently. I just remembered that Asgard wasn't done and went back but I can't progress the quest. I'm stuck on "bring builder's paint to the tower" part, but nothing happens when I do. I can't talk to the builder, all friendly NPCs are gone, Jotnar in the cave are gone/dead too. I was looking for a solution now and found hundreds of people complaining about this quest, is there any way to fix this?
