Hello!
I'm in Sovngarde, having completed The World-Eater's Eyrie. "Sovngarde" doesn't activate automatically. I walk around, run into the Stormcloak Soldier, who doesn't initiate conversation. I talk to him and he just asks me if I need something. So I walk around some more. I get the same response from everyone I run into. "Sovngarde" won't start. I try "setstage mq304 10" - nothing. I try verifying my game cache - it says one file fails to verify, so I restart the game, and have the same problem. I verify a few more times, always with the same result. I go back to a previous save - nothing. I disable every single mod and DLC - nothing. I'm to the point that the only thing that will allow me to advance the game is uninstalling and reinstalling (losing HOURS of game play), or using the console command "saq" which I DO NOT want to do. Or, of course, quit playing altogether, but I'm not ready to do that yet, either.
PLEASE tell me someone else has fixed this!
