CTD when click on "orbital bombardement" first and load a sav after

attached sav of related turn. When I first click on orbital bombardement, I get CTD (w/o dump file) just while orbital view is loading.
If I first do all other moves, I can click on orbital bombards and get the orbital view fine and can cointinue the game.

Win7/64, GeForce GTX780M, 4GB Vram, offline mode, single player

Update:
this above was turn 586, I continued the game w/o exit anymore until turn 609.
Then I made a sav, exit.
When I enter the game again and load the sav 609, the sav crashed along with a window Unhandled Exception and a dump file

I upload here the complete issue files: the first sav of 586, the sav of 609, the exception message, the dump file.
