Been trying to collect all the dragon priest masks and managed to get all 8 and kept them all in the same place. I did carry them round for while. But as I went to check on all the masks I couldn't see Krosis I'm pretty sure i didn't sell it and I looked everywhere for it . I also went back to Shearpoint and the elder dragon was there again, I killed him but didn't receive his soul. (Starting to wonder if it is glitch) Krosis' coffin was closed and I couldn't open it i tried shouting and attacking but it wouldn't open , really want this mask but I can't go back to the last save i had the mask because I've made so much progress since then. can anyone help?
