On the early morning of July 20th, 2012, the staff has confirmed that once again on Ship 2, the NPC positions in the Arks Lobby were moved around. Additionally they have confirmed the use of technics in the Arks Lobby. It is likely the suspect is using a different method than the last time to move the NPC locations, and the staff is currently investigating it.
The suspect isn't hacking nor cracking the server, they are making use of exploits, therefore it has no affect on your personal data. They will increase monitoring and continue to suspend the accounts of wicked users. They are very sorry for the inconvenience. If you happen to notice the NPCs are in the wrong locations, please change to another block immediately. They will try to address this exploit as soon as possible.
