Sims 4 deleted my current saved game and replaced it with my old saved game

So basically I went to one of my old saved games (My Saved Game 13) to get some NPC’s that Sims 4 removed off my current saved game (My Saved Game 15)  that I was playing on , as I was collecting them I made sure to NOT SAVE MY GAME simply because I didn’t want this problem to happen and weirdly enough Sims 4 STILL SAVED IT but in my current game which is weird because I didn’t save anything around 2pm I was only uploading my NPC’s to my gallery to transfer them over to my current game and now I can’t even play because it’s overwritten with my old saved game! Someone please help me! I don’t know what to do and I tried contacting EA but they claim they can’t resolve the issue, has anyone else have this problem before?

Also I’m playing on PS4 and my game is currently updated so outside of that this all falls on Sims 4 possibly having another glitch among the many they already have

Hi , I didn’t overwrite my saved game It was 100% on Sims 4 end it was basically auto saved without my permission on my current save and this is just one of the many issues I’m currently having on the Sims 4 but thank you for your response
