This issue might be better for Steam itself, but Steam support directed me here.
Underrail crashed once on a loading screen. I don't remember exactly where, but I believe I was exiting to the main menu. Since the crash, Steam permanently lists me as playing Underrail, even if I'm playing a different game. Steam won't let me launch or delete Underrail, or exit Steam because it thinks Underrail is running. I've restarted my computer and checked task manager, the game is definitely not running. Any ideas how to fix this?
