Greetings,

We sincerely apologize for announcing that new UI Update (Season4-Season5) will be postponed.

Game Client is still in development process and Server is in integration process. 

It is regrettable for users having waited for a long time to postpone this Update.

New UI Update will be released sooner or later and detailed information will be notified later.

Once again, we are deeply sorry that new UI Update is postponed and we will do our best to release as fast as possible.

Thank you

MU BK Team
