The most permanent way to disable scat is to disable the mod or remove the mod, you can disable the mod in the
Main Menu -> Settings -> Mods, it is called "Extra dirty" i think.
If you want to remove the mod completely you will find the mods here: ...\Bitch Land build10e\Assets\Mods
Remove the "Extradirty" folder.
The height thing have i never encountered, my settings stick, i often play "smaller girls" (between 165 - 169 cm) and their height stick, as far as i know, you cant edit height in-game after the Character Creator.
Edit: There will be a way to do body modifications in the clinic in a later build, but not now i am afraid.
