Hello. This is the Ragnarok Zero Operations Team at Gravity Co., Ltd.
We have identified an issue where connecting to the game is not possible when certain costumes are equipped, so we would like to inform you that a client patch was implemented on December 4th (Wed) at 19:12.
We kindly ask that you restart the game to apply the client patch before playing, even though this may be inconvenient.
We sincerely apologize for the inconvenience caused to your gameplay due to this issue, and we will strive to provide a more stable environment.
Thank you.
