Diablo 3 gold-duping bug found, auction houses closed for now

A gold-duping bug that has forced the closure of both auction houses should be fixed soon, but Blizzard has decided not to rollback the servers to pre-patch status, instead choosing to deal with the individual player accounts that decided to play fast and loose with the rules, namely don't exploit bugs you find.

After the release of the 1.0.8 patch for Diablo 3, some players uncovered a bug that allowed them to duplicate gold through both auction houses and gather billions--and in some cases, trillions--in ill-gotten gains, forcing Blizzard to close the AHs.

The bug has supposedly been fixed and is being tested, and the AHs will be back online once the fix is live. However, Blizzard has decided not to rollback the servers to pre-patch status, instead choosing to deal with the individual player accounts that decided to play fast and loose with the rules, namely don't exploit bugs you find.

"At this time (and after careful consideration), we've decided to not move forward with rolling back the servers. We feel that this is the best course of action given the nature of the dupe, how relatively few players used it, and the fact that its effects were fairly limited within the region," Blizzard explained on its forums. "We've been able to successfully identify players who duplicated gold by using this specific bug, and are focusing on these accounts to make corrections. While this is a time-consuming and very detailed process, we believe it's the most appropriate choice given the circumstances. We know that some of you may disagree, but we feel that performing a full roll back would impact the community in an even greater way, as it would require significant downtime as well as revert the progress legitimate players have made since patch 1.0.8 was released this morning."

The bug supposed resulted from Blizzard lowering the cost of gold on the real-money auction house from 25 cents for 1 million to 25 cents for 10 million. Apparently, when players canceled a gold auction, they would be refunded twice the amount listed.

      What a disaster of a game - really enjoying PvP as well.

              Not good enough for those who want visual-proc bragging rights for wiping out an under-geared group.

                Hey, I wasn't the one complaining about missing PvP. What you said is probably what it would be like and therefore I have zero interest in it.

              I guess? I thought it was basically just 4 people beating each other up, maybe it's only 2.

              Either way, PvP in games not built as PvP games from the ground up is pretty much always fucking terrible, so I've largely ignored it in D3.

              I really don't know. And there's a part where he logs in, gives someone all 64 billion of his gold, goes back to the AH and clicks something suddenly he has 64 bill again. IDGI

              2,000,000,000 max bid on AH, likely because 2^31 is the max value you can store in an int, which is probably the cause of the dupe bug:

                store in a signed int, that is.

                  Amusingly enough, apparently signed integers were also a problem in WoW: http://www.mmo-champion.com/threads/630417-Total-gold-earned-overrolls-32-signed-integer-and-becomes-negative-coppers

                    I wonder why they used signed integers for values like money. I can't think of a case where they need negatives value, is it something else? Performance maybe?

                      To be fair, unsigned would only let it go to 4B, they really need long ints.

                      More often than not those "decisions" are not made by any committee with some extensive performance analysis and technical justification.

                      Developers have a default type they use for integral & floating point values (usually int and double) and look for reasons to deviate from those. Depending on the time crunch, there may not be any more thought to it than "get it done asap."

              I think he's basically giving his gold away to people who put up the max bid on crappy items to screw up the economy

      I wonder if they banned every person who duped gold, if the result would be gold being deflated by removing all the good items that were bought by dupers and the overall reduction in gold.

      I remember using the belt bug in Diablo to dupe items. I would've been banned so fast if it was made like D3.

      Um, the caption for the picture regarding this article on the main page is misleading. It says the bug is fixed, no it's not. And this is not the same article title when selected from the main page.

          I wonder if they're going to delete gold from the system? They're already refunding all sales where people exchanged money for gold.

            I don't know how they walk the economy back from this:

            "I bought 12 gems for about $9 or so and dumped them all. Got about 1.2b from the sale."

            So gold was about $0.0075 per million.

              The non-existent economy will continue to be non-existent.
