So im trying to sell something at the Auction House. Now im trying to sell my "Sinister Skelly Suit" but the first time i tried it said "This item cannot be sold!" so i reailzed it had my Crest on it that i earned through i mission. So i went and took it off and tried again and the same thing happened. Now i though this item was Binded at that point so i went a took it to be unbinded and yet it couldnt be unbinded, because the option to wasnt even letting click on it, which i would assume means its not binded. So then i try to sell it again and yet that same message keeps popping up and not letting selling it.

Note: I got the thing when it was a Skelly suit and got recipes to upgrade it into the Sinister Skelly Suit.

If anyone has any ideas on what i can do. Or just heres whats happening and you cant doing anything about.
Then that would really help....
