With the patches being released, and Steam autoupdating, where can you find if your game has been patched. I looked in the game properties on Steam. I also looked on the main menu when the game starts. Can't find it. Can you find it within the game folders inside Windows?
I do not know where to look for it in steam, but ones you loaded a savegame then press the escape key.(If you are on PC that is, i do not know the button for consoles.) In the lower left part where you find the option like Save and settings and such you can find the version number...albeit in small dark gray numbers.
