I just finished fighting the giant mech after the part where you're supposed to go the 11th floor of the building but it gets ambushed and the glass cracks and floods the building. After that is a mech fight that i finished. I killed the mech with 4 c4's to the back of its head and it blew up. Chino and his crew come through shortly after and my primary objective states, "Regroup with Chino at central station: Regroup at the vehicles". I stand there next to chino looking him in the face, and he does not do anything. No one does. And the game does not progress and i've already tried restarting the game, resetting the level, etc. Can anyone explain to me what's going on? I can't even finish the game.
