I've completed the campaign under post human warrior twice now, and each time when I go back in the stats page says 18/19. Along with the 12/13 weapon attachment issue this prevents me from ever gettinf 100% for the campaign. Any others having this problem? When I finish the campaign I check and it says 19/19. But when I exit the game and come back in later, it's back at 18/19. Somewhat frustrating. Guess I should be grateful it's not as hard to complete as the boss level in Crysis.
