This is a small bug but after you cross the hallway and enter the room right before 173's Containment Chamber, Agent Ulgrin, moves around a bit and faces the wrong direction once the doors close.

Well, it's made on purpose. As you acn see, the guard rotates his head to your direction. We made it so that the guards doesn't do this weird rotating anymore.
And he's supposed to look towards 173's door (so he can see that the player enters it).
