While taking cuman to Rattae we stopped and he asked me to save his life if he will show me hidden treasure. I have chosen option to take money and take him to Rattae anyways. He have shown me some place in the woods, but I have not found any treasure there and cuman just walked away. Is it a bug or I misunderstood something?
the nearest stump contains the money. You shold talk to cuman right after you got the treasure out to continue the quest.
