Carbon Decay

Came back to say that until there is a fix, this is probably the best solution-- it's fairly easy to do, it doesn't reset any interactions with NPC in terms of dialogue, butr does cover everything in fog of war again, restores any killed creatures and loot in crates/chests/etc.

I'm with you guys, i got to the main hold and was like-- hey! let me explore around a bit for some sweet loot! left via the kitchen to the upstairs chapel, and can't get back down using any route possible. I couldn't possibly be feeling more salt than right now. close to 10 hours of playtime for me out the window until a fix comes.
