Starting the Jagged Crown quest with the Imperials, can't actually get past the ruins because there is a massive thing of rubble in the way. I did discover Korvanjund previously and went around in it. I assume that is why the rubble has not been removed for the actual quest. When I left the Korvanjund temple area and came back in, both Rikke and Hadvar had moved through to the otherside and so now I can't physically complete the quest.
EDIT: Instead of Stormcloaks on arrival there were bandits like the last time I went there. There was also only me, Rikke and Hadavar at the beginning when I fast travelled.
EDITEDIT: Have just noticed the quest glitch thread with this glitch at #73, so this is fair meaningless.
Hopefully that can get fixed up for 1.3.
Cheers,
