Recently, the Trade System has temporarily been disabled.
We have found several players exploiting the system to gain unfair advantage over other players during the recent Event.
As previously announced, all in-game abuse of the system will not be taken lightly and it will lead to permanent ban of your account.
We are currently working on tracking down the players who have abused the Trade System and preparing an update to prevent this from happening in the future.
We will bring back the Trade System back as soon as we could.
We apologize for the inconvenience.
