I have tried completing this mission 3 or 4 times now from the start. The mission has multiple objectives, a computer, then 4 generators, then Diabolique's phyactery, fighting Dominatrix, and then fleeing into the tunnels with a +16 level Marauder hot on your heels. Here's the problem: Master Midnight is supposed to teleport you out, but no matter where I go in the entire mission, the office building, the sewers, Cole's tower, the teleport never comes, so the mission doesn't complete and eventually a very angry Marauder finds you regardless of what map you are on. I am assuming some kind of prompt that causes a teleport and ends the mission isn't happening.
