Hopefully Nexon catches this quick.

If we do get rollbacked we'll probably lose the card anyway, to be honest.

Nexon really needs to take down the servers before this spreads any further. If they take it down soon they can ban all accounts connected and either do a very short rollback or just remove affected mesos and items from the economy. They have logs of transactions right?

The longer the game servers stay up, the further this will spread until a rollback is necessary. they really need to take the game down as soon as possible.
