There is no option to take the cuman anywhere.
I am only able to pickpocket him.
I’ve done this quest before in a previous playthrough and it worked fine but, it was in a patch prior to 1.10 on the PS4
Edit: I have not started the main storyline quest, all I’ve done is persuade the Rattay guard to let me in the city, I’ve been sidequesting and doing other misc stuff ever since.
I believe that you actually have speak to the bailiff in rattay to be able to move the Cuman there and get your reward.
Ok so I called out the translator for lying, learned about the treasure, found it, and gave half to miller, I can’t speak to the cuman and he is just there in the shed. So, in order to move the cuman I have to talk to the Rattay bailiff?
If you had the Cuman take you there you then can take him to Ratty and get a reward.
You need to take the Cuman with you to get the treasure. You then have a dialogue option and a cutscene that shows you putting the Cuman in a jail cell. Then collect the reward from the bailiff. I hope this helps.
