Hey Guys, I have another problem. Actually I am trying to save some files in the onDisable, so they are being loaded in the onEnable. The problem is, that they aren't saving in the onDisable method. I don't know why... The void is being executed but the first for() isn't. Is it possible that my ArrayList has already been removed? How can I save a file in the onDisable? Because it just doesn't do anything.
