I just played Insurgency: Sandstorm earlier today, and then left to do some other things. When I came back to start it, Steam said it was already running, even though it was not. Restarting Steam fixed it, but then when I opened up the game again, it would not connect to the server and was laggy, so I went to restart it to see if that fixed the problem, but then Steam again said it was still open. I close the game using the quit button in game, and there is nothing in task manager to say it is still open. Steam won't close properly (I had to use task manager). When there is a game that is not open that it thinks is open, is there any way to fix this?
