Child, Toddler, Infant Presets/ body sliders aren’t working for months now

We don't know if the game change that broke the Child and younger presets and sliders is actually fixable without causing other game bugs -- and that's not unlikely, given that there were game bugs with Child and younger bodies! Because mods are not officially part of the game, I also don't expect the studio to answer that. They're not obliged to make changes so that certain mods work.
