I've killed 2 of the 3 dragons in At the Summit of Apocrypha, I'm riding Sahrotaar but cannot control him, fast travel, die, read the black book to respawn in Skyrim. I'm completely stuck, and to make matters worse, the last save that is recognized is from 2 months ago (eventhough I save religiously) .

Anyone have this problem before? What can I do? I'd rather not walk away from this game, but there is no way I'm going back and replaying over 6 MB of the game I stand to lose.

**Update*

I was just able to kill Sahrotaar, but I'm still just hanging out. The quest won't continue.

You don't have to control him. Just ride, then kill enemies, and once you reach Miraak. Land! One known bug is that Miraak kills a dragon to get healed, but you get the soul instead of him. To avoid that make sure, that Miraak stands closer to the dragon, than you.

Miraak is nowhere to be found.

Omg. That's good to know. Thanks! I'm almost at that point.

I sent an email to Bethesda. My guess is that I'm screwed by some glitch. So the three months I played the game is now lost. Was level 49 with 48% finished. I'll either have to go back to about 12% finished or quit playing this game.
