Ive been trying to set up a creative server on a flat world however it firstly wouldnt change world type to flat but would accept the texture pack I was giving it and the game mode. I messed with it for a while but then the texture pack stopped working and it wouldnt let me set the world to creative. So the issue now is its just a regular survival world. Ive tried resetting the world, repairing files however neither have worked and im stuck with a survival server that occasionally doesnt start.
