After installing Hearthfire, I notice random NPC's stucking everywhere.

Example:
You are trying to marry an NPC, the wedding finishes as it should.
Then you move out of the chapel and back in, all of the NPC's who attended your wedding are just stuck there and wont be moving anymore for the rest of the game.
They wont move to their original location either.


I've tried fixing this with console commands and unfortunately nothing works.

I currently have a save game totally useless because of this issue.
Anyone knows a fix or has the same issue?
