I keep a symlink to Public\Games on my slow hard drive that point to my ram ssd with all the working copies on it - which, of course, failed to update due to the symlinks. But since the ram drive could lose everything at any time I kept a plain unaltered "Games.real" directory on the slow drive with no symlinking in it for quick reloads. So one point to Acard for inadvertently saving my butt from a complete reinstall.
