I'm not sure where to copy from and to. I copied both from worlds_local to worlds in appdata, but that didn't seem to do anything. I'm assuming that's where they're saving on the dedicated server because the files always update to the dates we've played, but I'm not sure where I'm supposed to have the data files to play them locally.
