I was playing around with Sunset Valley, and (maybe this is more of a bug
![Huh ???](https://www.carls-sims-4-guide.com/forum/Smileys/default/huh.gif)
) Hank and Pauline had three children when I was playing with them. I got bored, moved on to another house, then went back to them, and the third baby was a toddler and disappeared. He wasn't killed off, (I checked the newspaper), and he wasn't "kidnapped" by another household. My ultimate guess, was that he gotten taken away by the social worker? It was most likely a bug though.
I've had the Keaton's move into a bigger house 8 out of 10 games, after the baby was born, and their unborn child moved in with Claire's unborn child while they were dating. But they were still teens! I've had this in Riverview with Bob and Betty Newbie.
Don Lothario, (the TS2 town Casanova) seems to end up in more relationships with men than women, 9 out of 10 times with Story Progression on, usually with Hal Brecknage, Jedidiah Wilson, or Billy Caspian. In one game, he moved into the Lobo's house, and one of the twins were killed off. 9 out of 10 times, Constance Shelley is heavily pregnant every time I see her. I've had Dallas Shallow and Laurel Grisby date quite a bit too.
This is exactly why I stopped using EA's story progression as soon as I discovered Nraas.
