Game not saving progress all of a sudden after closing and reopening

KimieM80​  To be clear, the new save is fine (still, after a day and restarting your computer), but the old saves constantly revert progress?  Does ALL the progress revert or just some of it?  And do the modified dates on the older saves update too, or do they reflect the last time you successfully saved?

Thank you for your reply, As for the new save, that is golden and nothing has reverted back as of YET! As for the old save that I mentioned in the OG post, everything reverts back to the past that I used as for my family and lot bc I was still building on an empty world at this point, sorry I should have specified that before (all saves in the lineup were affected by whatever this was). The modified dates reflect the time stamp of when the files saved and didn't automatically adjust.

KimieM80​  Sorry, I just want to make sure I understand:  The timestamps reflect the last time your progress was saved, or the most recent time you tried to save but it didn't work?  The reason I ask is that these are very different issues.  The first means the save is probably corrupt, although there are a couple other possible explanations; the second means either the save process is breaking or the newer file is being replaced by an older one.

Every attempt to save has reacted normally during the saving process. The timestamp reflects the time that the save was performed regardless of it going back in time or not (if that makes sense). I had to make a back up copy of my saves once I found the issue happening. The new save continues to save normally, I just checked it and it is where I left off from 3 days ago when this issues started (I haven't played since this happened while I try to find out why it happened). All of the old save files continue to revert back to one specific time in the past. I hope this better explains things

KimieM80​  That does explain it, thanks.  I just wanted to make sure this wasn't a case of OneDrive or some other syncing service replacing your new saves with older ones.

It's definitely possible that the affected saves are corrupt, and in fact that would be my guess.  However, one thing you can try is loading the save in a new admin Windows account.  The temp files from an unzipped save are stored in a hidden folder that's unique to a given account, and we've seen a few issues with this folder recently, although the problem is usually with all saves.  Still, it wouldn't hurt to test.

Create a new, local, admin Windows account, load the game once in that account, quit, and add your save to the user folder there.  (You can drop files in C:\Users\Public to be able to access them from any account.)  If you can save your progress, great, try the newly-saved file in your old account.

If the save still doesn't work, go here:

C:\Users\[USERNAME]\AppData\Local\Temp\Electronic Arts\The Sims 4

While the game is open, you should see a scratch folder inside the Sims 4 folder, and a scratch_[numbers] folder inside that, containing a large number of files from whatever save is loaded.  Sort the folder by file size and let me know how many files are essentially zeroed out: 1 kb or less.  This is one clear symptom of a corrupted save, and it would explain why the changes you make don't stick.

I'm so sorry I thought I responded already, I'm glad I came back to check! I did the admin windows as you suggested and checked the save and still all 5 saves revert back to the old point so my husband and I think it's a corrupt save as well. The new save is exactly where I leave it each time. I think what I will do is just scrap everything, save all of my lots and sims to the gallery, uninstall sims and start fresh so that any bugs that may attach to other saves don't stand a chance. I've had sick saves before but this one's a first. I really appreciate your help and dedication to finding out what happened here. You're e gem :-) Have a blessed rest of your week

KimieM80​  I think you're right that your saves are corrupt, but I would be careful transferring data from them to a new save.  Just test everything first, before you spend any other time building the new save, so you find out about any potential problems right away.  We've seen cases where a broken lot can break a new save too, even one with no real progress other than placing a few builds.
