MapleSEA got Tempest

apparently [MENTION=5956]hadriel[/MENTION]; was right, it was hacked.

Dear Maplers,
It has come to our attention that there is a glitch to
produce items that can be easily upgraded, cubed and enhanced through the MTS system. To protect the general interest of all players, all players who are currently holding such item(s) will have their account trade-blocked until 12th June 2013 server check.
A total of 81 Maple Accounts will be affected by the trade block until 12th June 2013 (post server check).
During the server check, developers will be carrying out reinstatement of the items to its original state as of 15th May 2013. No compensation of consumables and cash items will be made in conjunction with the reinstatement. For further enquires, do send in iBox for assistance.
