So Steam recently did some kind of client update and after restarting it and going to play Spiral Knights, it was missing from my game library. I tried to go to the page on Steam to download and reinstall it, but it simply refused to- it would show the download progress for a split second and then stop and say that Steam was downloading it and that I could check the progress of the download etc etc. Well, I figured I could at least use a shortcut, so I picked "Create desktop shortcut", but when I ran that, it simply went back to the first download screen and made me try to download it again.
