Dear Gunz2 players, Recently the 'Nickname Change Card' Problem is reported frequently. The problem is that when a player uses this item, he can't add or delete friend after his nickname changed. Further if he is a Clan master, he become to lose the right of the Clan master, and can't use the function of Clan master. So, please be careful when you use this item. (Actually, we recommend not to buy or use this item until this problem is resolved.) Sorry for your inconvenience. Have a good day. Thank you. Best regards, Gunz2 Team
