To be clearer, because I realized I skipped past the explanation to the fix, I was thinking of things like robots and otherworldly beings with no human genders when I left that, though I don't want to say that humans can't fit under Other or that non-humans (including robots or otherworldly beings in different canons than the ones I was thinking of) can't fit into M F or NB. Any genders that would normally fall under non-binary were meant to move with non-binary!
