Apologies that I wasn't able to solve this for you three in time. I have been informed by the studio that there will be a second chance for you to enter the Soda Cup starting next week which will give you a new chance to participate!
Although I got a "second chance", there was a problem with the game's network connection and the mission suddenly disappeared. Hopefully things will be back to normal during the game.
I have a second chance to,but there is still a problem with king server,my home page has completely changed and can't chat to teammates,when is this going to be fixed
