Someone posted about this the other week and I thought it might just be a visual thing, but I've seen it a few times now, and it's now showing on my app...
As we all know, the best way to make coins in this game is to trade, which means that many of us have unassigned items, and unless you use the glitch to open packs in unassigned, they have to sit there dormant for a while.
Now whatever your thoughts on unassigned and trading are, because I'm aware that some are critical of it, if packs are expiring, it is completely unfair.
Many people stack packs for TOTY, TOTW or other promos, in fact some good threads have been on here about such things.
Ultimately, this could affect everyone if it is true.
