Ok I screwed around with this a bit and at this point I'm not sure this has anything to do with the mods. I still don't understand what is going on.... So I got another save where I disabled and reenabled mods to see what would happen. I got to the Arboretum and everything is looking alright. With All Natural-Real lights on it is as dark as it is supposed to be. So I saved my game, loaded all the mods from the screwed up save, and reloaded the saves to see what the hell is going on. 1) If I load the non screwed up save first (it's also at the arboretum) and then load the screwed up save, all of a sudden the screwed up save isn't screwed up anymore, no washed out colors, everything dark exactly as it is supposed to be. 2) If I load the screwed up save first, it stays screwed up and if I try to load the non-screwed up save afterwards the game simply crashes. 3) I loaded the screwed up save, went outside the arboretum and saved. If I load this new save and go to the arboretum, everything is still screwed up/ This is without removing or changing any mods. Weirdest thing ever. So I can load a non-screwed up save, reload after it a screwed up save and somehow the problem is fixed? What the hell is even happening here? Anybody knows?
