In the sweetest way possible, if all you lost was a few hours then I don't see why you're (apparently) so very upset. Many times I have seen contributions worth days or weeks of work dismissed from software projects. For that matter, in academia you can spend months or years working on a result only to find that someone else has been working on the same result simultaneously and has published it before your work was complete. If it's only a few hours I'd honestly just file it away under experience and get on with my life. Not taking sides, just putting it into perspective. Ben. :)
