On June 5, 2018 I've activated a burn coupons from the link http://maplestory.nexon.net/micro-site/ark/vcare2 . However when I logout and login a couple of hour later my burn coupon seemed to disappear. And Yes Ive read ( http://maplestory.nexon.net/news/31543/complete-scheduled-maintenance-june-7-2018 ) the article about the maintenance and how it was suppose to fix the glitch however until this day I haven't gotten my burn coupons back. I've check my inventory (use, equip, cash, etc) the gift icon, and i've also tried retweeting about it but nothing seems to work.
If you have any clue how to fix it please leave your comment below.
