I'm not sure wether this is intentional or not, but for some reason, you are not allowed to use the command /i or /gm (Gamemode) while in the spawn of Flatland. As I've said, i'm unsure if this is a bug or not, but I would just like it if all commands were enabled in this area. I'm not sure if there are other areas like this, but I would think it would be quicker to get to your destination quicker if you could type /I feather inside spawn instead of flying out to type the command.
