Re: Lost everything in update
@lillameetamart Strange, everything's where it's supposed to be. Even the save that's currently showing is in the same place as the ones that aren't.
Try loading one of your old saves in a clean game folder. Move the entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop. Launch the game once to generate a clean folder, but don't start a new save. Just quit at the Main Menu. Go into Saves inside the Sims 4 folder you moved, right-click on the Slot_00000002.save file and Copy, then right-click inside Saves in the new game folder and Paste. Then open the game and see whether your old save appears.
If it doesn't work, delete the save file you copied over, and repeat the process, except with the Slot_00000002.save.ver0. Be sure to delete the .ver0 on the end, so the file now just ends in .save instead. You can try to access all of your old saves this way.
If none of this helps, do you use mods? Did you with these old saves? It's possible, although still unlikely, that a save that had been exposed to a mod that's now gone (or disabled) would no longer load.
