no need to worry about not giving a screenshot, I wasn't expecting one and thought you'd just type it like people usually do lol. (not complaining tho screenshots are almost always helpful.) and another question, have you completed the Bareshade expansion and Mythshore storylines?
also what happens when you try to go to the murcad cave with Scar? does he just not show up, does the game give a warning does it say you need something to progress when at the cave? and have you done the eavesdropping Gunnar and Everett's conversation mini event?
