I'm trying to get the completionist trophy in ac valhalla, everything was going fine until I was doing the Lunden mysteries, specially de Cynewulf and the other 2 musicians, I got all the 3 people required at their spots and then went to the concert to end de mystery, but whenever I go to the square where they are playing music the end never triggers and if I go to the place between the public where it says "interacts" my Eivor just gets stuck and the end of the mystery never happens, I still have a bit to do, but I would like any advice on how to solve this glitch, it is pretty annoying and I don't have a backup save for more than 15 hours, that I don't want to spend again around the map grabbing stuff and solving mysteries
