Neverwinter suffered an Astral Diamond dupe exploit a few days ago. The devs caught wind of it, shut off the Auction House, and rolled everyone back 7 hours. For inconveniencing everyone, they handed out Apology Packs containing useful items.
Twas a very smart thing to do, considering now there isn't any residual duped currency in Neverwinter.
