I am attempting to change the default end world. I am having trouble trying to do so. I have tried simply overwriting the directory that the default end is saved as with another end world folder that was customised in single player, but it doesnt seem to work. Now, I know this isn't exactly plugin development, but it kinda is too. I am wondering whether there is a way to do this without code, or if I have to replace the file with Java, not even sure if that would work. Has anyone tried to do this? Does anyone know how this can be done?
