Assassin's creed Valhalla (PS4) bugs for me at the quest "A brewing storm".
The game asks me to go to sleep, my screen turns black for a short while, no cutscenes are played.
Afterwards Dag just wanders around town being attacked by everyone. Keeps being revived and fighting again, this cycle is endless.
I have tried to restart the game, and return to a save file before the bug occurs. None of these solved my problems.
