My friend and I just got done fighting off some Cabal when the mission bugged. Instead of normally completing the mission upon defeating the commander (like most missions), nothing happened. We scanned the area for possible enemies hiding, but as you can see, no radar activity whatsoever. After investigating for a few minutes, we figured it was a bug and aborted the mission. Wondering if anyone else has had this problem, and I'm hoping it gets fixed in another patch.
