After killing Wigmund at the Ely monastery I go back to the camp where there is a cutscene in which Galinn is taking Birna hostage (yes I made the wrong choice killing If in the quest Treacherous Stench). Then follows a fight with Galinn where, unfortunately, I keep killing him and he becomes revivable and there is just no end to it. My only manual save is right at the cutscene and I tried 10 times to defeat him but he just won't die and I cannot move on. I tried to tp out of there and then I couldn't go back to the camp because it became a desynchronized zone. Please help, I really don't wanna restart the game.
PS : I have a video of the fight if needed
