I agree. I already used the terminal suggested by Mirole prior to crossing the bridge the first time. When I interacted with it, it a first would not allow me to use the items to repair it but after clicking on it again, it was suddenly repaired and I could no longer interact with it. As I did this prior to finishing everything, I figured that was the end of it but the elevators did not activate and I could not call reinforcements. Now, I can not finish the quest as there is no NPC to hand over the Calcaduceus to.
