Re-named sims

This past weekend I came upon a glitch while playing my long-running game. I've never seen this happen before, but maybe someone could shed some light on the situation. Or maybe someone else has experienced the same?

So, I opened my game and went to play one of my families (I play many households) and noticed that two of them were renamed as deleted premade sim names. Sim "A" and his son "B" were renamed Ekram Elderberry and Thomas Jabari. I opened CAS and sure enough, they were renamed there as well. I even restarted the game and still had the same problem. So, I just changed them back to what they were. Nothing else but the names were changed. Then I played a bit more and nothing else happened.

However, when I went to play again this evening, I started playing with another one of my households and found that my sim "C" was renamed to Victor Feng and his wife's last name changed to Feng, too! She got to keep her original first name.
I should have taken pictures, but I was eager to play and annoyed enough to change it back right away. If it happened again, I'll take a screen shot.

Sorry, I didn't click on "Gameplay Mods", I think I accidently scrolled down somehow. I meant to tag this in the general forum.
