The database of Hearthstone was damaged in China – but there is a compensation and details about the card distribution.
Anyone who invests a lot of time in Hearthstone has certainly built up a considerable collection of cards over the years. How frustrating would it be to finally draw the right legendary card from a pack after long collecting and hoping, only to lose exactly that card because the Hearthstone database has an error? That is exactly what happened in China. After a power outage, the databases of Chinese Hearthstone players were damaged.
4 Days of Rollback in China pays off for players – 25 packs for free
Blizzard was unable to revert the damage and had to reset the database to an old state – 4 days of gameplay were lost in data nirvana.
Affected players will not be left with their losses. Blizzard has announced compensation and will provide affected players with a payout worth nearly 25 card packs. That means: 5 classic packs, 5 from Whispers of the Old Gods, 5 from Gadgetzan, and 1,000 gold.
Before and after the rollback, the contents of packs were not the same, but something very similar
However, the incident also had something educational; as suspected from many sides, there is a predetermined guarantee to receive a card of rarity X after a certain number of packs.
If someone had a legendary card in the 5th pack they opened before the rollback, they would also find a legendary card in the 5th pack after the rollback – even if it was a different one, it was still one of legendary rarity.
This could mean that while the cards are “re-rolled” upon opening, the rarity of the cards is predetermined.
