Nightmare update breaks game
Can't get into Cas. I can't even start a new character without turning all my mods off. Its simply a white screen and that's the way it stays. I would have paid you half the price of this new pack...
Move your Mods folder to the Desktop and delete localthumbcache.package. Then test the game in a new save.
If it works now check for updates to your Mods and CC. Add it back a little at a time while testing until you have found all that are broken.
