Hopefully Nexon catches this quick.

It's not looking likely we will get one at all. You'd think if Nexon was going to do a rollback they'd do it before a 2x exp event, because I can imagine some very angry people (myself included)

Which I'm sure is what the hackers plan for. They know Nexon doesn't work on the weekends. The more delay there is in a response to such exploits, the less likely there will be for a rollback, thus more profit for the hackers :I
