So every time i go through a portal i get put into survival, which is fine because im opped. i have a world for creative and want to make it so when players join that world they can press a button on a command block and turn into gmc. i put in [ /gamemode creative @s ] and it comes up with the message "player not found" when i re enter the command block. does anyone know what to do? (I've also tried turning command blocks on and off in the properties tab and restarting the server with no luck)
