i found two orange items ingot and another in vendors on GL shard about a week ago. i dont care who sell what, unless its a scam for innocent people.
these vendors dont say its event rare or server birth like you see in scam vendor. buy it at your own risk, as usual.
but as someone said, its from an exploit and can be made.
*edit*
you cant make orange metal item from the ingot. but be sensitive to orange items without special name and property.
