Here's 2 of my previous Sims that keep changing shapes. Odette is the worst affected in image 1. She has average fitness skill and I left her with a slimmer frame which I'd shaped by adding curves. But her hips now look out of proportion to her body, it's about 6 months since I last played her household.
The second image is Cinnamon and she has maxed fitness skill. Again I'd added curves to a slim frame and left her household, but she keeps changing to the maximum size. I keep trying to reshape her but her face keeps changing too. I'd just like them to stay the same when I switch households.
@SqueamishNerd I never touch the custom body sizing, and only occasionally use the muscle/fat sliders, but I’ve always seen the same. Minimum regular exercise = extremely thin very quickly no matter how much cake they eat. No official exercise = extremely fat quickly, even if they spend half their life starving and only eat salad if they eat at all. The logic is terrible.
