sims 4 save files

@aab2305fde9a290c  In case you're not already aware, when you use "save" (not "save as"), the game creates a new save file and demotes the previous one to a backup.  It only keeps the five most recent backups, deleting the oldest the next time you save and demoting the rest.  So if you routinely use "save" and never create new save slots, you would only ever have files from the six most recent times you saved: one main save and five backups.

IS this what you're seeing?  Or are you missing some backups too?  Is OneDrive running on this computer?  Even if you never use it, OneDrive can mess with your saves and other user data.
