During the mission where you have to overload the powerplant to bring down the AV with an EMP burst, we entered the compound and I quickly downed the drones. However, we kept driving in circles without the mission progressing.

If you encounter this bug, turn on your scanner. As you go past one of the gates, there is an automatic turret that is hard to see without the scanner. Even though it doesn't seem to be shooting at you, or even if you already disabled it with a quickhack, you still have to manually shoot it with the truck turret and then the story will progress.
