save files in game overwriting?

Is anyone else having issues with your save files in game since the update? I started a new save file yesterday to test things out with the autosave feature.

 I decided to open a different save file (one I don't care about, was just a randomness file) to change the save settings to save reminders only. I saved and went back to the main menu. NOW it shows in that save file the sim from the file I made yesterday for testing, and what I had originally in it is now gone.

Screenshots below are of the save files in game as they show right now. The top one that says Planet Sims is supposed to have the female sim in the second screenshot as an active household on slip 42 in Strangerville but she and her home I made are gone now.

If you need any other information please let me know and I will do my best to get it for you and if I should edit tags. 

Edit to add: I was able to recover the other save and have switched back and forth between that and the new one. Exiting out of the game, changing save settings, etc. Seems to be ok now. Might have been just a random mini glitch? idk. Just wanted to update! Will still be holding off jumping into any of my favorite saves for a bit though.
