I have a survival world that I am trying to change to creative (because I have a ton of unfinished buildings on that world which would take forever for me to get all the resources for) but when I use the NBT Explorer in MCEdit to change the game mode to creative, when I go into the game it will say in the singleplayer menu that the world is in creative but when I load it it's still survival. Can anyone help me?
As it turns out, I spent all morning fiddling with it only for the world to stay as it was. I even tried copying a playerdata file from a creative world but it still reset. Also opening the world to LAN and switching game modes only changes the game mode temporarily.
