This was very weird.
You encounter and follow Puca, then you have to survive a fight with it.
I did, and then it was standing there, back in wolf form. Marked red as enemy, but not attacking and not taking damage.
So following it as the quest wanted was impossible. Reloaded, same.
I still found the site, and killed all, including Puca.
After finishing I got an avenge quest. Blackwoodz of all people, a well known AC youtuber.
Found his corpse, searched for the perpetrator - and it was puca again. Alive, not fighting, not taking damage.
I reloaded before game got off track even further.
Anybody else had this?
