Game automatically removed from Steam library



Yesterday, after updating to the latest version, I started the game normally and played around for an hour. Shut down.


Then later, when I turned on my pc, I started the game via the desktop shortcut (normally I would open steam, then press ‘play’). The game didn’t start. I double-clicked the icon again and it said: ‘app already running’. So I thought the game had probably hanged itself. Reboot and voila! After rebooting, the game is listed as ‘Not Downloaded’ in my steam library. 

I checked /.steam/SteamApps/common and star conflict is still there (i.e. 789 items in the folder, 4.0GB)


I’m using Ubuntu 14.04 LTS x64


I’m re-downloading the game now.
