Please fix the problems with the Blue Archive event (Inven, opens in a new window)

The poster took issue with the fact that the Ayane and Iroha set in the 50,000 won Special Supply Pass during the Blue Archive event is only available until the Challenge server launches. They said the hair coupons and cosmetic surgery coupons are time-limited, so they can't be used on Challenge server characters, and demanded they be made permanent so they can still be used after the Challenge server ends. On Inven (opens in a new window), many said that while exchange tickets can be time-limited, coupons should be permanent, and there were follow-up comments asking for the cosmetic requirements to be loosened.
