If you haven't been watching, the Mean Streets of Gadgetzan packs from Hearthstone's [Free] latest expansion came with an unintentional bug that made the drop rate of tri-class cards higher than intended. Well, Blizzard has just announced that a hotfix has been rolled out to all players on the Americas server at 2:30PM PST, and that should correct the issues. Any player on the Americas server who opened Gadgetzan packs prior to 2:30PM PST will receive additional packs as compensation. If you were one of those affected, you will receive 33% of the total amount of Gadgetzan packs you opened prior to 2:30 rounded up, regardless if you got the packs using gold, real money, or from quests. If you bought the 50-pack bundled and opened all of the packs before 2:30, you'll get an additional 17 packs.
