[raiguard][2.1.9] Crash on closing the game (segfault in AsyncScenarioSaver)

[Laar]

Crash during the closing of the game, after playing for about an hour on a multiplayer server.

The last things I did were:

• Saving the multiplayer session
• Maybe a few things in between
• Exiting multiplayer
• Closing the game via the exit button

To see if it is reproducible I loaded the game again and directly pressed the exit button, that did not crash. Neither does loading the saved multiplayer and exiting after that.

Platform: archlinux, steam
