From what I know, story progression hasn't been working for quite a while. With the weres, as long as they are in the were form, they don't seem to age. When I play in MF, the Wolff children have stayed at the same age while my sims children have aged up and had kids. The Willima (her name ?) was a child still when my founder sim's granddaughter was in school.
You can change it, I think in options, for control of supernatural population and stop them from becoming weres, but they will still stay in the were form, still not age up.
I had wanted to get rid of the stupid behavior of acting like a cat, clawing at the furniture. So I thought that the pop control would stop that.
*sigh* it doesn't
Fairies are fun to play, but if your sims doesn't have a sense of humor, they don't like to have the pranks played on them. They make good gardners, great to play if you are planning on having it as a means of income, growing food.
