MapleStory Europe recently launched a sale on various cash shop items. Among the discounted items was a series of double experience cards lasting for varying durations, each marked at 15% off the usual price. It wasn't long before players noticed that Nexon had listed the 24-hour double experience card with an expiry time of 90 days instead of of 24 hours. Players flocked to the item shop in droves to take advantage of this amazing deal, many suspecting that the item must have been a mistake. Sure enough, Nexon noticed the mistake after a week and removed the item from the sale.
