This is not something that can ever be fixed, unfortunately.
Like the other height mods, this does have clipping issues in game. Can be found by dragging the side of the hips up and down. Hip shape slider. Adjusts the shape of a Sims’ hips. This can be found by dragging the neck in profile view up and down. This can be used with or without the height mod, but there will be clipping issues between Sims of different neck heights. Adjusts the length of the neck, simple as that.
The slider and preset are Teen and older only, as kids and tots have awful distortion when trying to adjust height. You can find this by going into the Body Presets section in CAS. Four different height body presets, Short, Medium Short, Medium Tall, and Tall, are also available, in case you don’t want to manually adjust the height yourself. It can be used by dragging the neck up and down from the front of the sim. The Height Slider Mod introduces the possibility to scale a sim’s body.
