Are players crafting items from future patches?
As I understand it, the server is currently emulating 2.0 content.
On the auction house, I've noticed people selling http://www.wowhead.com/item=32776/cr...-the-sea-witch, which was supposedly added in 2.1, and http://www.wowhead.com/item=33122/cloak-of-darknes, added in 2.2
For Crown of the Sea Witch, this is supposed to be taught by the Jewelcrafting trainer, but the trainers do not currently teach it (which, is to be expected).
So, how are people obtaining these to sell? I don't see anything related to this in the bugtracker, but maybe I'm searching the wrong terms.
