When I first tried this game, I experienced a glitch where The game kept running while minimized, but had switched to a background process that I couldn't ALT+TAB to. This only happened once and I'm relieved. But now, with the new update, I'm having a more serious problem where whenever I minimize the game, It doesn't just close, the Executable Completely disappears without a trace. I can't even find it in the recycling bin.

Make sure you set the game to Borderless Windowed mode. it looks just like fullscreen, but when you alt tab you wont have these issues.
