If you put the black gear dye on it doesn't change the color at all, it stays the same. I can tell what it's supposed to look like per if you remove it, it turns black for a second the goes back to the regular color of the gear.
Wow this whole time I just thought the black gear dye sucked like it was pretty neutral because i could never tell when it was on the gear unlike the pink! glad to know my black gear dye is also broke! Please fix this so i can be the cross bow of death wielding ninja I was always meant to be? lol
