Spoiler
the game just crashes, it's happened three times in the exact same spot. getting Martin to the Temple, just as he defeats Mehrunes Dagon in his dragon form and then is about to (I think turn in to a statue)
Normal things I might do like toggling the AI to see if it's to do with NPCs I obviously can't do as that would effect Martin so I'm bloody stuck, so some help would be nice please peeps.
