On Ship 2, they have confirmed that cheaters have managed to change the positions of several NPCs on certain blocks. Since they will have to reset the affected blocks; If you are playing in a lobby and notice that the NPCs aren't in the right locations, please switch to another block immediately. They are currently investigating the situation and so far none of your personal information has leaked out.
Since the Open Beta Test, they have confirmed around 75 accounts of individuals using cheat tools and real money trading (RMT) services. These accounts will be permanently banned, and from now on, any account that is caught cheating will be quickly banned.
When you find players who are cheating, please use the "wickeduser" report form and send a screenshot with their Player ID number attached.
