I did some weird thing where my own stupidity is what saved it. I had closed Sony Vegas improperly and it did an autosave because the program shut down before it was finished. I originally said no to opening the autosave project a split second before realizing it was my CVV vid that had been saved. I googled and found that I could still pull up the timeline. Then I redownloaded and converted the source, plugging it back in and adding in the last render I did of the project where the timeline wasn't filled in.
