@kormac67 was there also a solution for this? because anything i tried as of now, doesn't work

I need Help with the Puzzle at Berker-Moor, were you fight that thunder Witch. the first time i fought her it was fine, i searched the corpse, the event triggered and the witch spawned so we could fight ( at that time she was just too powerful for me so after a while i bailed out)
Now everytime i try to trigger the event again, it wont let me interact with the hanging corpse. So i can no longer fight this witch an therfore cannot get the full set of armour for thor, and also later cant get the hammer of thor. please help
