Save file not loading in game

@nicki_sims15  The issue is the -MSI in all the save names.  Sims 4 can only read saves if they're named in exactly the required format: Slot_ followed by an eight-digit hexidecimal number (base-16: digits 0 to 9, a to f) followed by .save .  These are all valid save names:

Slot_00000002.save

Slot_0000000a.save

Slot_00000015.save

So remove the -MSI wherever you find it, and the saves should show up again.  If you get a warning that a file with that name already exists, cancel the rename and make sure to change the save's number too, for example you might need to change 00000003 to something higher.

The .verx extension denotes a backup copy of the save with the same number.  These are viable saves as well once you delete the verx .  So if your most recent save doesn't work, try one of the backups.
