I've had saved the game three times, and one of them was using the autosave slot. I've left the game idle for a while and I am assuming at what was the autosave interval (5 minutes?) it prompted me with a dialogue to choose if I wanted to overwrite the game saved on the autosave slot. (image attached)

I chose the "overwrite" option, at which point the screen became black and there were some rectangle shapes on the screen that seemed to react (flashing) when moving the mouse. (other image attached)

I could not recover the game from that point, nor bring up the GMM, so I had to Alt-F4 to exit the game.
