Can't complete Main Quest :/

Did anyone experienced CTD at the end of the MQ? I read that there supposed to be a video at the end...

It's repetable and it happens when certain large entity turns into stone (?)

Did not find anything particularly wrong in Message Logger log...

Finished the MQ line 3 days ago, no problems. But I don't have any mods with custom armors and weapons, and no mods that change races or facegen, pure vanilla only.

I've only finished the main quest once. I experienced no problems.
