Because of the New Update, Gamemodes are disabled now. Please go to my thread in the Suggestions area and please support to remove the new update, which would mean you can go back to the normal creative gamemode and etc.
None of us have permission to force change your gamemode besides opped users (Cypriot & Crew) You'll have to email [email protected] and hope for the best.
Thread locked on request. If you disagree to this action, please report this post, and a moderator or administrator will reconsider it. Kind regards, The Staff
