Odd steam bug

Hello GSB community, I’ve been enjoying this game for awhile now and now that the Galactic Conquest add-on is up on steam, for some reason steam says i have it. I did not by it and it doesn’t have the campaign in the main menu. (it has the " you own this! click to play now!")

This is a steam bug, I’ve notified them. Stay tuned…

Good, for a moment I was the only one with this problem.
