Trivia

 * In this event, the Wailing Wall, which gives the player's XP multiplier a 2.25% boost, could for several hours be bought for just 1000 in-game money. It allowed players new and old to rapidly increase their XP multiplier with ease resulting in extremely fast levelling, enormous amounts of in-game cash, and very easy donuts. The Wailing Wall price was later patched to the correct price (50 donuts) after EA became aware of the mistake.
