I was taking the 2x exp out of the cash shop but then my client crashed. When I logged back in the coupon was gone. Neither in my inventory or in the cash shop inventory.
There's no record of you purchasing a x2 EXP coupon today. You might have lagged, and the server showed you a message that you bought one, but your NX was not deducted (you did not lose any NX towards a purchase of an EXP coupon).
Yeah, I didn't buy it today but I didn't take it out of the cash shop until today. But taking in what you're saying and how you're saying it. Ima assume that the moment I bought it is when it activated haha. My mistake. Thanks for the reply!
