Just hopped on after a long day looking forward to playing some deadlock, and noticed after I launched that it said the game required an update. Naturally I update it, but the update notification is not going away. I have verified the game files, Uninstalled and Reinstalled the game, and ensured that steam is up to date. Nothing is helping. Also, I am not the only one faced with this bug, as I am talking to 2 other people as I write this report with the same issue, but it is not happening to everyone, as I have friends that are actively playing games. Hope to see this fixed soon.
