Pink Raincoat Armband needs the armbend_pink_g_co texture but does not have one, it is either using armbend_small_pink_co or armbends_pink_co

Here is a variant I made in a couple seconds (no version exists currently)

There is also an issue with armbends_pink_co (though I am unsure if it is used or not as there is a version of this with the same texture but is fixed named armbend_small_pink_co)
