Once i played like an hours, and i wanted to save the game, but the "Save" button in the menu list is gone, i could only see the "save & quit", so i press it, but it says "you cannot save the game while the auto saving is in progress" and i think it should be save by auto save, so i close it but, when i open the game again, it didnt save my game and i need to redo and recraft my mission and weapons .... please help
