Harrison, who of course has a habit of screenshotting almost everything he does, has of course sent a ticket to Nexon about his overall expiring. He also posted a thread on the Nexon forums. He wants his overall back, as well as the costs of the item lock refunded. Hopefully they both happen. If the worst happens and he doesn't get it back, he did manage to make a very nice black oriental fury coat from Maker which he will scroll. Hopefully things will turn out right, because Nexon DID recognize the issue after all. It'll probably be a while before we know, because Harrison's away for the week. Either way, this should never have happened.
EDIT: Also, Harrison told me the same thing happened to someone else he knows.
