My game deleted everything??

So I just updated the game, and when I restarted the game it deleted literally everything.

None of my households or houses are there.. completely starting from 0.

All of my cc that I downloaded is not showing up in the game either.

I checked my mods folder to see if my content was still in the folder, and it is, so I really don't know what happened or how to fix it. 

Kinda sad that all my gameplay is lost tbh... 

Is there anything I can do?
