I'm just going to pull the entire folder and play vanilla. I'll remove everything, mods and cc. I never touch my long running saves until mods have been updated. When we get big patches like this I just start a new save or a tester save to play around with while waiting for updates. I made a whole new family just for the new EP so I'll have them to try the new features out with. Well, all I'm waiting on with them is for the patch so I can add an infant to their family and they are good to go.
I don't anywhere near my long running saves until mods are updated. It's pretty much a given that lots of things are going to be busted and it's just not worth taking the chance.
