@parakeety21 Sadly no, dead NPC has disappeared and mystery isn't completed. Tried numerous workaround, but nothing is fixing it.
Hello,
Upon assassinating the man, the completion did not trigger. I'm unable to redo it through an earlier save.
Restarting the game or reloading a save does not solve the issue.
I'm left with this only one mystery to complete, then I'm done with all mysteries.
