Total Security is glitched but I also didn't do the mission in the way that the game described. I turned off two of the generators and climbed up anyways, I think that my game switched missions on me so the third generator didn't appear on my map anymore so I didn't turn it off before climbing up. Got shocked a little but not enough to kill me. I went to the roof, found the recorder and turned off the transmitter. Did a few more missions before I realized that it wasn't a turn in mission to a NPC. Went back and turned the third generator off and climbed up and no recorder this time. Mission is still sitting in my Quests menu. Gonna have to try it again on a NG+.
