There is a bugged console in the Defera Power Plant (Easy level) for the mission Power Hogs. In zone Bravo, the rear left console does not count toward mission completion. This is the mission that requires two consoles per zone, inside the Power Plant, to be modified by the player to shunt power away from Borg systems. Zone Bravo is the only one with a defective console.
The bugged console is circled in the above screenshot. The player is able to activate the console and complete the modification to it, but the mission simply ignores that console - requiring that the player move to a third console to gain mission progress for Zone Bravo.
