Currently there is a problem with the "assets enlargement".
You can modify your character's body measurements using the Shrine's interface. But if you max up certain parameters (ass size, for example), the looks of your character will be reset when you load the game next time. The numerical values will remain the same as you have set them to, but the looks change back to average. And you'll have to revisit the Shrine to repeat the procedure just to restore the modified looks.
I guess it happens because the devs are trying to find a way of avoiding the clipping issues. (Take a look at the 2nd screenshot to see the sword not compatible with the ass.)
So, I suppose that if you edit the parameters to make certain body parts even bigger, their visual representations may be back to normal upon restart, and you'll have to edit saves again and again.
