Latest Sims 4 patch deletes the entire world of Willow Creek! :(

I was building in willow creek and all of a sudden my game crashed. Now willow creek will not load it just gives a blank white screen when I click on it. It's like that in all my saves even new ones. I have repaired the game removed all mods etc still the same. But when I remove the entire sims folder and start a new game it works. Help please!!
