Except for my NL character(IGN: POLYANTHUS), all other characters have got 1.5 exp coupon And every day i start my quest, i would open my NL at first, so I’m pretty sure that NL has done daily quest every day.
Okay I can see an issue here due to a full inventory problem. Your character POLYANTHUS did complete the quest 23 times, and was marked to have been given the coupon, but the coupon does not exist in your inventory. The script is checking to ensure you have 1 of each slot free, and if you were to be given an ETC item alongside your coupon, then the inventory operation would have failed but still marked as having the coupon given. We will look into refunding you a 1.5x coupon for this issue.
