Yobit update: They replied to my ticket and told me to submit the addcoin form, acting as though I hadn't done so already... I submitted it again, but I'm not sure what the deal is over there...
Ditch Yobit completely imho, they are one of the worst exchanges possible.
Better try Cryptopia or Novaexchange i think they are of the most reputable small exchanges, then Bitrex.
