sims 4 body changes (sliders, hips, legs, etc) not saving after I edit them

I Do not have any mods but every time I edit the sims, either through manage household or in live, the body slider changes do not save, I csn change things like skin color, hair, clothes, and etc, but I can't change their body shape, as soon as I exit or save the world snd rejoin, any changes are immediately reverted. It's been a while since I played, and I wanted to enjoy the new expansion pack only for this bug to crop up and irritate me.
