In Duma Key, several things have happened.

Nick Lothario had been having a very secretive affair with Frida Goth. His wife Adriana finally found out and threw him out of the house.
Brad Burb got drunk and did something very disgusting, and his wife Tiffany threw him out.

The teens have been up to things, too:

Johnny Burb and Daniel Pleasant have fallen in love, having discovered that they are both gay.
Mortimer Goth is in love with Mary Sue Oldie.
Bella Bachelor is rather taken with Don Lothario.
Brandi Newbie is rather fond of Michael Bachelor.
Skip Broke likes Jennifer Pleasant and Nina Caliente.

Thus the 'canons' of the game are getting blown up all over the place.

I used Nopke's character creator to create 10 townies for my town. It seems to try to overpopulate the area with redheads. (Only one of them is a playable Sim right now)

I also used Nopke's character creator to create townies for my military base and noticed so many redheads in town. Good thing I like redheads! I do love that mod because (a) it's so easy to create townies and (b) I think the townies come out looking very interesting, with a lot of variety (except maybe hair color).

Well, my Romance Sim certainly finds quite a few of them to be very attractive indeed.
