Krosis, the one at Shearpoint, will not come out of his tomb. I found out many many people are having this problem and a lot can't find solutions either. Some say use Unrelenting force or hit his tomb with a sword and he appears, but none of that works for me. On a second note though, the shout word wall behind his tomb is glitched also, for when you approach it, it plays the music it would if you were obtaining a word, except there no glowing word, no trail following, nothing, it won't let you get the word. I would really like some help on how to solve this since this makes me unable to get the final dragon mask.
