Why are so many random sims shaped like a pear?

I haven't had this problem very much recently! There are even completely normal/attractive npcs being generated. Body shapes + faces. I'd say one out of every three generated townies in my game can pass for normal now. I think the clothing generator has been improved too, because most of my sims now age up with at least half of their outfits being acceptably fashionable. Bravo to the person/persons behind the changes. They're much appreciated. I had to pause and stare recently, when a John Stamos look-a-like appeared on a lot to bar tend! Only out of shock, of course ;)
