Re: how to bring back my saved game

What @puzzlezaddict said, I'm afraid.  ☹️  Your saves, etc., are all stored on your hard drive.  Only things you specifically upload to the gallery are elsewhere (and that's not a save, you could download your household and your lot but you'd lose your progess, what was in their inventories, what was in the household inventories, any rockets would be unbuilt, any upgrades you'd done would be undone...) 

If the shop didn't (or couldn't!) save your files, they're gone.  ☹️  (Depending on what was wrong with your computer, it's possible they couldn't.  Specifically, if it was your hard drive that died.)

This won't help you now, but going forward you can copy your saves to a thumb drive whenever you finish playing.  I'm a paranoid IT person, so I back up my entire computer AND manually back up my saves.  I had a horrible hard drive death some time ago where I lost EVERYTHING and was traumatized.  You could also manually copy your saves to dropbox/onedrive/google drive if you don't want to mess with a thumb drive. 

(Another advantage of manually copying your files to a different location is if you need to "roll back" because something bugged out and you didn't notice it right away, you have some versions from the day before if none of the rollback versions fix it.)
