Why are so many random sims shaped like a pear?

@Simpkin I downloaded from another page which is no longer accessible, but it looks like this is the same thing, posted June 2018. My download from over a year ago still works after all the recent updates, so this should be good:

@QueenofMyshuno is it defaults/overrides or just extra?

@Simpkin I believe it’s default override.

What's funny for me is when I'm creating Sims and their body looks normal, but is actually the pear shaped one pulled to match the others. I'm not the one doing this, the game randomly does it.
