I went on a mad deleting spree and I think I may have deleted something I needed. My game won’t save unless I save and exit the game. My sims house all disappeared.
Is it possible to tell if I deleted anything crucial?
I compared the files in your screenshot to my files and everything is the same except that I have a Mods folder but it looks like you don't. However, it is possible I still missed something. You said you can't save unless you Save & Exit. What happens when you try to do a regular save without exiting the game?

Not from the screenshot you provided. Can you remember what you deleted? A screenshot of the contents of your saves folder would help. How to take screenshots (not photos) https://support.apple.com/en-gb/102646
