I can't start the fourth mission in sequence 7 because I didn't continuously play mission 3 and 4. While I was playing the fourth mission I needed to turn of the PS so it didn't save the game. Now I can't start mission 4 because after mission 3, that I already completed, you go directly to the bunker hill and I can't replay the memory of mission 4. Every time I replay mission 3 I am being brought after I complete it back to the place where I clicked on the replay mission button. Does anyone know how I could play mission 4?
