Hello, this is Natara.
We have completed server maintenance on June 19th (Tues) from 4:00 AM to 6:20 AM (GMT+9).
This server maintenance was for the server’s stability and expansion. So there are no new changes in the game that needs to be mentioned specifically.
We apologize for not informing you with a notice beforehand for performing server maintenance during the early morning. We hope you can understand we wanted to provide users with stability as soon as possible.
We will do our best to provide better service.
