I've been using Premiere CC for a while now and finished up a couple videos recently where I haven't had to go back to an auto save file. Today during my edit Premiere has been acting glitchy and I've lost some of my work. Now I can't find the auto save folder where it normally should be, in the same folder as the project file. The project file is there, but the auto save folder doesn't have any of the project's files. The setting for auto save every 10 minutes has been checked off this whole time.
You can now set this manually in the Scratch Disk settings. Check there.
