So i have had Assassin's creed brotherhood since December and finished the game. However, still more than half of the achievements do not show up. What i find even more odd is the fact that in the achievements it says that i have completed sequence 1,2,3,4 but completely skips over 5,6,and 7 but says i have completed 8 and 9. Clearly this is impossible for i cannot finish the game without doing the middle portion. I need assistance because this is really starting to aggravate me.
