Didn't know how to tag this, sorry if Settings/Options isn't the right category.
Upon closing the game, Steam still says it's running indefinitely, and the same happens when clicking the big Stop button (it stays in the "stopping" phase indefinitely). My play time also keeps increasing as if the game is still open. I made sure the process is closed in task manager. I have to kill Steam in the task manager and then reopen it in order to relaunch the game.
