Q: I've accidentally deleted a wtex from the female folder and now it doesn't show up whichever wtex I copy back in there.
A: Copy the desired wtex in the female folder then restart your game.
Q: I switched to my toon's swimsuit. The chest changes but the hips don't.
A: Copy the desired hips wtex to another folder and rename it to F_Hips_Bare_02_D.wtex then move it to the female folder and you'll have that texture for your toon's swimsuit.
