a new expansion to the hit card game Hearthstone is cause for much celebration, in some corners it's also been cause for consternation as players have struggled to buy the right packs from the in-game store. This and other expansion issues got so bad, in fact, that getting these CS requests sorted out forced Blizzard to slightly delay Goblins vs. Gnomes' European launch (although it is now live in that region).
The problem, as dismayed players and streamers discovered, is that the default pack purchase option in Hearthstone's store was for the base game's cards, not the expansions. Gung-ho players would then accidentally mass-purchase a whole lot of packs thinking that they were from Goblins vs. Gnomes, only to discover that they just wasted hundreds of dollars on cards they already had. Touch Arcade has come to the rescue by pointing to a handy guide how to buy the right packs for the expansion.
