I started a non-blocking save and before it was finished, I immediately quit to the main menu.
The game correctly switches to the main menu and there is a progress bar where the normal main menu would usually be.
But as soon as the progress bar is finished, the game crashes. (The save completed successfully though)

Instead I expected to get to the main menu once saving was done.
It seems to always happen consistently.
Reproduction steps:
- Enable non-blocking-saving in the "The rest" menu (Ctrl + Alt + click settings)
- Load a game (normal freeplay in my case)
- Pause the game, click "Save game" and save it and while it is still saving, click "Quit game"

This has happened to me as well, I wonder if simply disabling the quit game while saving would good enough.

Thanks for the report, this has been fixed for the next release.
