CAREFUL, SPOILER

Hello,

I'm currently working on the Alduin's wall quest and I'm up to the point where I have to go the Sky Haven Temple.
Well, the thing is, I had already discovered Karthspire and managed to go to the entrance of the temple before. So, when I got the quest with Delphine&Esbern, I went directly to the top and found them here. Spilled some of my blood on the mechanism and opened the door (the big face).

I can go inside the temple but the two npcs are not coming. Tried to wait/sleep and nothing. Went back to Karthspire and found them stuck at the first bridge with the little enigma. Speaking with them has no impact.
Did anyone had the same problem and managed to fix it? (I don't have any recent save. Auto and quicksave are "after" the bug)

I have the same problem on the PS3. I'm 50+ in and can't finish the game!

I found a way around the glitch! If you don't fast travel to sky haven temple and start the quest at karthspire camp and fight the dragon and then walk all the way to the temple with esbern, they won't get stuck at the first puzzle!
