Re: Help Recovering Lost Data
@i_flerb No, unfortunately there's nowhere else to look. EA doesn't support cloud saves for Sims 4, leaving only the local copy of the user data. Since you wiped the computer and OneDrive doesn't have a backup (please do look in OneDrive's recycle bin if you haven't already), that local copy is gone.
You might be tempted to use a data-recovery tool to try to find the save, but I'll tell you that I've never seen it work for Sims 4 saves. Even the paid tools don't recover enough data for the game to use the affected saves.
