This quest marker for, and how to get there

deus-ex-human-revolution

I'm currently attempting a side quest called Cloak and Daggers, and I'm trying to get to a mystery quest marker that appears in my HUD but not in my map. I've been wandering around for about 15 minutes now, trying to figure out how to get there.

As you can see:

The marker seems to be inside the building. I can't find a way inside. I checked the map on alternate levels but the marker doesn't appear on any level of the map.

Here's a view from another place, looking at the same marker:

But here's where it gets really strange. If I stand in certain places, sometimes the marker moves elsewhere. Here's a set of images with the marker in a different location:

It must be part of the "Cloak and Daggers" mission, because I have no other side missions available. I am tempted to believe that it part of the objective labeled: NEUTRALIZE ALL MCB OPPOSITION. I have killed everyone near that original objective except Double-T, who I knocked out, yet that phase of the mission is still not marked as complete.

What is going on, and how do I finish that objective and get to this marker?

That's a bug in DE:HR, it happened to me, too. One of the gang members has wandered off to some point where you can't reach him. I would point you to a specific website, but none of the suggestions I found helped directly.

Otherwise, google for deus ex cloak and dagger bug and try out a few things.

I opted for the possibility that the gang member is one another roof somewhere and tried to shoot him (without seeing him), but that didn't work. All out of a sudden, the marker started moving and he was back in the flat, so I could finish him off.
