Hey, i'm sorry if this was asked already, but using the search function i didn't find it.
My question is, at some points during the leveling, opening the gift boxes gives you a +12 coupon. I could use the first one just fine, but since then all of them just say "Not Upgradeable (Duration)" when i try to apply them.
I know they didn't work in the Pre-Open Beta, but in the Open Beta the first one at least worked. So any ideas? Also i just got this voucher so it can't be that the time is already running and it just ran out.
