Hello,
I've encountered a very strange and specific problem. My latest save is at just after 6am on Fredas 14th Sun's Dusk. I can do everything, including rest, perfectly fine before the in-game clock ticks over 8am. As soon as the in-game time goes past that then saving, waiting, sleeping and fast-travelling all cause a straight crash to the desktop. I've racked up 117 hours of gameplay with no problem so far, but this is really preventing me from going any further.
If it helps, the most recent quest completed was to retrieve Enthir's staff from Southfringe Sanctum. My latest save is in Helgen, on my way back from that quest. I was attacked by vampires the night before my latest save, but there's no mention of me being infected with anything under active magic effects, so not sure if that has anything to do with it either.
I haven't installed any new mods for several weeks either.
Skyrim version is the latest with all official DLC.
I'm really stumped, any help anyone can give me on this would be gratefully received.
