Hello, This is the Gravity Ragnarok Online: Zero Operations Team.
After the May 18th regular maintenance, it was confirmed that under certain conditions, equipped items were not being unequipped/equipped properly in a single action. A client patch has been implemented to address this issue, and we are providing this notice accordingly.
We apologize for the inconvenience, but please restart the game to apply the client patch before playing.
We will continue to strive to provide a more stable service environment.
Thank You.
