[3.1.2] Saving project exception after cancelled Vista shutdown

[Crimson Wizard]

This is quite an exotic one. Found in 3.1.2, haven't checked 3.2 RC yet.

I was shutting down my laptop with Vista, while AGS Editor was still open. Vista told me there are applications that are still working and gave an option to cancel shutdown to close them properly. I hit "Cancel", opened AGS window, hit "Exit". AGS suggested I save a game. I hit "Yes". Following exception occured:

Code: ags

Error translates to english like "There's no reference to object in the instance of an object.". Sounds weird for me, but that's literal translation. Then again, I am not much profecient with C#.

This should be resolved in the 3.2 betas.
