CLicking the share button in the referral advertisement spins authenticating to Facebook and returns error 104. This is ubuntu 14.04 with steam.
I have the same problem on debian steam.
I was advised to be logged in with a browser. But still got same error even with all available browsers logged in to facebook.
Ok, so after the last update when I clicked the share button a browser window opened, asked for me to login to facebook, forwarded to an available port on localhost (don’t remember the port number) then failed as usual.
Debian/Steam
For me the entire game freezes. I had to xkill Star conflict, and the station sounds, explosions and ships flying by, kept playing.
