I went to work on a project I've been work on. I still had the project open but the session had expired. When I refreshed the screen I came up with a design that was many days older. It seems I've lost days of work, is there any way to get back to where I was. The projects link is https://www.youtube.com/watch?v=KhlJp1VZMB8. Project name is "Tom's Fog Buster" . I've done so much work on it lately I'm not sure I can recover from this. Any help would be greatly appreciated.
Lost current design
