Hi,
right now if you want to look for a kuyak, or a heraldic mail, you can't post an offer being sure that the item you're requesting is the one you want, as there are more than 1 item with the same name. Also if you find someone offering a Kuyak or Heraldic Mail, you can't be sure which one he is offering.
So please, rename those items to make a difference (p.e. Light kuyak and Heavy Kuyak, Long Heraldic Mail and Short Heraldic Mail), and we will be able to trade them correctly.
Could also be applied for color armors, like mail with surcoat, transitional with surcoat or coat of plates, just putting the color before the name.
