I play SOTM via Steam and immediately noticed the misspelling on the back of the Industrial Complex environment cards. It's even MORE obvious there because a blown up image of the back is used for the wallpaper while you are playing. I was curious to see if this was the way the physical cards were printed too and a quick look through the gallery confirms this. But even more odd is that it doesn't appear that anyone has ever noticed it... or more specifically, nobody has ever commented on it. I guess I might never have noticed either if I weren't playing the game blown up on a computer screen!
