I have a weird problem.I went to the dwarf king before i got the quest from King Mark and he gave me a signed treaty.The problem is the treaty is flegged as signed by both.Now i got the quest from king Mark and he gave me the same treaty which is signed only by him.So now i have two treatysne signed only by Mark and one signed by both.But i don't get the option to give the right one(which is signed by both) to king Mark or to get king dwarf to sign the one Mark gave me.So...i'm stuck at the main quest.Also,how how do i solve the the quest with the father&son who forgot the right combination to open the chest?Pls help me-at least with the main quest.
