Have you ever found a solution? I’m in exact same situation except I don’t know for certain I ever had it in the first place. I defeated Sarevok but might have knocked him out instead of killing him. When I go back to the murder tribunal the question marker is still there but all the bodies are gone (everywhere else in the game bodies are still there).
I checked the box on my camp, and it had a lot of items missing. I dump a shit load there, so perhaps amulet of behaal too.
Really bumped out, this is my first play through 150 hours in and it seems like I can’t finish the story now??
