As described by (some) others, you will likely not be able to finish the game. Others say this only affects the GOG version, but I am not willing to pay hundreds of bucks to compare one and the same game on different sales platforms. Suffice it to say, at some point in the game, it will crash, and after that, necessary scripts won't be triggered any more. The door remains closed, and that's it. Restarting the mission will not fix this, only complete removal of all save games and restartin the game from scratch. FRUSTRATING to the max - do not buy, save yourself.
