The error happened during printing of the packaging for the new March of the Machine: The Aftermath Bundles. The bundles have displayed a picture of March of the Machine: The Aftermath Epilogue Collector Boosters as part of the Bundle, which is incorrect (see "Brand New Details for 'March of the Machine: The Aftermath'"). WotC will remedy the issue by applying stickers to affected bundle boxes to correctly display the March of the Machine: The Aftermath Epilogue boosters that are actually in the bundle. There is a possibility that this will delay March of the Machine: The Aftermath Bundles in certain regions, but is unlikely to impact North American distribution of the product.
