So you own the Sup Com gold edition with the Addon FA? You only wrote that you bought SupCom.
I own both Supreme Commander and Supreme commander: Forged Alliance, I don't know if it's a Golden Edition or not as I bought the CD half a decade ago. When I activated it on Steam (before we had to link the FAF account to Steam), those two games were what I got.
Get the public url of your steam profile and open it in in a browser without being logged in. Can you see it? Does it show the Games button publicy? Is Forged Alliance listed under those games? (not under recent activity)
Aye, it seems like Steam is at fault here... I can't see my games, even though I put them on public more then 12 hours ago... I guess me wanting to play as soon as I reinstalled the game was a far off dream ;-;
Should I try contacting Steam or just wait? (Just to be clear, the games are still public on both profiles, as the settings attest)
