I got the quest from the miller, told him I wasn’t interested in his scheme and would be taking the prisoner to Rattay, and paid him in advance. I got the aids to unlock the shed for me and found the Cuman inside. I spoke to him but didn’t take him to Rattay immediately as I had something else on going. When I returned later, the quest guide tells me to “(Optional) Take the prisoner.” and the marker is in the shed where the Cuman WAS (I saw him there the first time I visited), but he is not in there now.
If there is any way to find him or at least clear this quest off my log help would be appreciated. Even if it’s with mods or console. Thank you! I’m on PC.
