So how does the save to disk and load disk work and how to get the uninvited event if that is what it is called
I don't know what you mean by "the uninvited event," but the save to disk function is pretty simple. You click "Save to Disk" in the menu, then it'll prompt you to download the save. Keep that save somewhere you'll remember, and then when you want to load it click "Load to Disk" and double click on that file, wherever it is
