I am having problem completing the manhunt due to a bug at the waterpoint control point. After killing the 1st boss, the 2nd part of the taking over becomes bugged. either no mobs came or the boss does not appear. I tried 3 time and 3 times no enemy came.
Same happend to me in the recent manhunt. Fast travel to savehouse and back to your allies (the green pistol symbol) fixed it for me. Still a bug though...
