I noticed the last time I played, one of the twins (they are still Child age) has gotten a tad chunky. I also noticed that my Global Superstar (even though I use MCCC and his physique is flagged) has gotten a bit fuller of leg than he used to be. I may have to take them all back into cas.fulleditmode and fix them. I don't use the flag on child Sims, or Toddlers, although the fifth child, still a Toddler, has also gotten a bit on the chubby side. The others children never did this, in this age stage. They also are very active children, they have age-appropriate play yard items and can often be found playing even in the snow! This could be something the patch blew up, as I do recall this problem being prevalent ages ago, too.
