If you received any mystery Arcane Dust recently or have been missing cards, Blizzard has issued a statement to clear up what exactly happened.

  • Some players obtained extra copies of cards that they should not have been able to.
  • A process that was ran last night was done so with errors, which added extra dust to accounts and removed cards that weren't supposed to be removed.
  • Blizzard continues to work on a resolution for the issue and will then start the process again.

Read on for all the details.

Hey all,

We’re working to fix a few ongoing issues right now that we wanted to give you all more information about.

Last night (Pacific time), we started a heal-up that awarded many players some Arcane Dust (starting in the Americas region). That Dust was to compensate those players for a bug that allowed those players to get extra copies of uncraftable Golden cards from various sources, like monthly awards, Arena awards, and some products (but not Packs).

Those uncraftable Golden cards included cards from the Rewards Track and the Battle for Alterac Valley event. The heal-up was supposed to delete the extra copies of those uncraftable cards and award the affected players with Dust equal to the value of those cards. That’s why different players got different amounts of Dust—it depended on how many of those extra copies you had, and what rarities they were.

Unfortunately, as some of you have noticed, there were some issues with the heal-up. One issue was that several cards were included that weren’t supposed to be included, resulting in players getting more Dust than intended. A second issue was that some players got the Dust award twice. A third issue is that some players had too many cards deleted, leaving them with fewer copies in their Collections than intended. When we noticed these issues, we stopped the heal-up to avoid causing issues for more players.

The team is currently working on fixing these issues. We just ran a script to correct the Dust grants for people who got it twice, and are in the process of running a script for people who got too many cards deleted. Once these issues are fully resolved, the team will run a check to make sure the fixes have been run correctly and all appropriate adjustments have been made. Then, we will finish the initial refund in the Americas and start it in the other regions.

We will update this post when we have more information.
