Developer Cryptic Studios and publisher Perfect World took the astral diamond exchange and auction hall of its massively multiplayer online game Neverwinter offline to "resolve a high-priority bug" that involved a currency exploit.
The cheat allowed players to duplicate astral diamonds, the in-game currency bought with real-world money. Users reported the exploit in the game's official forums, according to a report on Massively.
The game's publisher, Perfect World, has locked threads about the exploit and taken action against a number of accounts that allegedly used the bug. Suspected cheaters will receive email notifications, while users found guilty may have their accounts either temporarily or permanently banned. Players who believe they have been unfairly caught up in the issue are being urged to contact customer support.
