This mission can bug out when you have to disable the 3 turrets by destroying their power sources. After I destroyed the last one, it came back online seconds later and the power source cannot be destroyed again and the mission cannot be advanced.
I see old threads about this on google and it's still a thing. Only solution is to restart the mission and hope it doesn't happen again (and it happens late in a long mission). Don't see it on the known issues list.
