whenever i preview a mask and take it off, lipstick is poof. even though i did this, the glitch still occurs. i changed them all to what you suggested just in case. on top of that there's three or four different lines within the customization items.xtbl file that contain the mouth etc etc line. i'll need a more thorough explanation on what exactly i'm changing in which customization.xtbl file, as there's one just called customization items.xtbl and one called customization default items.xtbl.
I did what you suggested and it didn't work. i'll try this and get back to you if it worked
