"Disappear" means it is running, you are leaving it without any interaction from your keyboard or your mouse and it "closes" itself without any notice after some time. There is no intentional code for this behaviour in the software. The problem started to appear just after 2017 Win10 upgrade. Our software has been in development since 2008, is written in C++ and several latest versions were compiled by Visual Studio 2017, but not the latest version. We test the latest VS version this week. This off-topic paragraph was written just to explain that some problems can lay outside of your/our possibilities - with Microsoft being responsible for them. I play the latest X-division properly installed on Windows 7 Ultimate SP1 with latest updates, AMD Phenom II X6, 8 GB RAM, nVidia geForce GTX 460. But I need no help as you clearly said there's no guarantee for GC saves, esp. when saving frequently. I just wanted to mention that the loading freezing still exists.

Just a small not about crashing/disappearing. I work in a big company working on PCs with Windows OS. Our dedicated software started to "disappear" without any notice or a crash note just after an upgrade from Widnows 10 v. 1511 to v. 1703 and later. It seems having problems with some new (or changed) way of work with memory on new W10 versions. I found a note about similar strange memory behaviour of later Windows 10 releases at the web page of 7zip: https://sourceforge.net/p/sevenzip/discussion/45797/thread/e730c709/ Our software needs upgrade to change its way of work with PC memory and it may be a similar cause also for other software, incl. games. Back to X-div: I have registered many freezing during loading of ground combat (at approx. 95% of progress bar), almost all my GC saves were done just after start of my turn. When I press ESC during the freezed loading screen, I am able to go back to the main menu sometimes, but the game is broken and crashes. I have to go 1 GC save back to continue playing, sometimes more. Of course I'm using only manual saves, no autosaves.

GOG + latest XCE version + .41 mod: sometimes freezes during loading of GC saves from GC missions, today even a GC save (a terror mission in this case) from the main menu. The second try after killing the process and restarting it again was OK. Strange. Something not initialized fast enough? Also many errors in log file about MODEMERGE of laser weapons: Sun Sep 10 13:08:07 2017: Xenonauts, version .
