So I've done all of the things this mission has said for me to do, yet it won't let me complete the part that says "Neutralize all MCB opposition."
First of all, when I first attacked the apartment, I used tranq darts on all of the guys except the main target, which I knocked out using the non-lethal take-down. This didn't clear the objective..
So I went back and shot each of the guys with my machine pistol except the main target, knocking him out again. Still not clearing the "Neutralize all MCB opposition" objective.
I'm at a loss here.. I have tried everything I can think of. The way-point for "Neutralize all MCB opposition" is telling me to enter an apartment complex I cannot get in when I look for it on the map, and when I crawl through the tunnel going from once side of the map to the other, the way-point actually moves position. When I stand on the emergency exit stairs outside the MCB apartment, I look and see the way-point floating in the air above the buildings about 86 meters from where I'm standing..
