Well first of all, this is the second time I've played through on the same character because my file got corrupted once. (I lost her entire family with that one. *cries* )
My Lily is a flighty, punky blonde rock star with traits of being flirty, a great kisser, and the Master Romancer lifetime goal (WooHoo with 5 different sims in 5 different places), so she's a bit of a Casanova. Basically, she achieves eternal youth via sleeping around. And she tends to have flings abroad. Funny thing is, I've noticed that when you travel back home without breaking up with your foreign love interest, they seem to just stay your love interest forever. (Which unfairly causes your sim to be a "cheater" when she shouldn't be, but whatever.)
Anyway, in the last game, Lily went back to France with her two grown twins and since this loading screen is like 5-10 minutes long I usually do something else. I came back to discover that Lily's last name went from Nyx to Bernard! What?! There was no message explaining what had happened, no memory documenting whatever had happened (although her memory book got filled long ago anyhow), nothing about this in the scrapbook notes, etc., and she was sad about someone's death. It took me foreeeeeever to remember amongst all her paramours that she once had a fling with a French guy named Yves Bernard. It seemed that Yves Bernard was now dead (which makes sense since she had time to go home, have a relationship with another guy, have twins with the other guy, and the twins were now adults). I figured maybe the game made her marry him out of respect because he died and she was so brokenhearted over it or something. No clue. Tragically, the twins' vampire daddy Wogan Hemlock died during her pregnancy, so there was no other "long-term" guy in her life anyhow. I was a bit miffed that the game took the liberty of changing my sim's last name from Nyx to Bernard, but whatever. Figured next time I moved the family I could probably change it back, because Lily Bernard sounds stupid.
Then my game got corrupted and the twins are forever gone and I cried tears of eternal sadness. I mourned my lovely half-vampire half-human boy/girl twins (Tellullah and Jaime Hemlock-Nyx), started up a new game, and tried to find another suitable guy around town for her to start a new family with (after achieving Master Romancer/eternal youth again, natch).
Now Lily Nyx II is almost at the same place her much cooler predecessor was in. Sadly there are no cute lifemate material guys around my new town, but she did meet this one guy who looked interesting because he had dark skin and blond hair so I figured I'd make her have a pretty baby with him anyhow. This time I decide shortly after the baby is born that I should probably travel back to China and properly break it off with the guy she WooHoo'ed with once who apparently thinks they're still in a relationship. Y'know, before he dies.
I didn't have the foresight to not go afk during the loading screen this time. I come back to my computer and Lily Nyx is now Lily Kim. LILY KIM. LIKE THE RAPPER. Uggghhhhh.
Luckily, the creeper who thinks he's still her boyfriend is still alive this time. Elderly (and bald), but alive. And his last name isn't even Kim, so that's weird.
What's weirder is that the local Kim household has a blonde child who is listed as Lily's daughter! What?! (Blonde! Have I mentioned this is in China??)
So somehow, the last time Lily was in China, she must have had an affair with someone in the Kim family (which neither she nor I recall) and uh, knocked him up? And then when she returned, they forced her into marriage and to claim responsibility for this kid she did not know she had?
I am so confused. I wonder what the currency exchange rate is for child support payments made to China in Simoleans. Or if I can adopt her and bring her home with me. At least Lily II has a very culturally diverse family...
...Okay but for real, does anyone know why this keeps happening? I'd like my Sims to not run off and change their names and have secret illegitimate daughters without at least telling me a compelling WHY.
