New Update Broke My Game

Hello, after the new update when I go to save it will look like it saved but it doesn’t. After twenty minutes of putting a room together for the third time it just crashes and deletes it. One of my pack legacy saves is completely gone. I preordered the new packs and can’t even play them. It doesn’t matter what save I’m in, or what I’m doing in game it will not save and it crashes every single time.
