Diablo 3's Auction House is back online after Blizzard took it down earlier this week, following an update bug that allowed players to duplicate trillions in gold. Blizzard found the bug, exterminated it, and will now donate all proceeds generated from the exploit to Children's Miracle Network Hospitals.

Blizzard will not roll back the servers across the board, but will instead target specific accounts that used the exploit, banning or rolling back those users depending on their activity.

"Only a relatively small number of players had the billions of gold necessary to exploit the bug, and only 415 of those players chose to use this exploit for personal gain," Blizzard Production Director John Hight writes in the Battle.net forums.

As of yesterday, Blizzard had recaptured 85 percent of the erroneous gold and was working to track down the remaining currency.
