You know what's even better? If they can record how many packs each player got and if they can add and remove items at a heartbeat once they found an "intended" bug,

they could probably reset all fragments from everyone or find a way to balance things and THEN bring back the packs so everyone has a chance to redeem the same amount.

Why they didn't do that? Probably too much work and effort, better vent that work and effort planing the next ingot event, deleting posts or find new ways to frustrate the players.
