the bug is on the character packs. i made one for a trans girl long ago and it is kind of bugged unless i change the gender to fem and the femboy actions are a scrap character pack that i shared with Decker 666, and it has the same bug if you try to use it as a npc too Still, if you want to use the character pack, it is, of course, for a male, but if you want the boobjob, you need to use it on a female/shemale, but the bug of trans npcs means that for it to fully work normally, it is on female npcs.
