Final Mission Bug

[JESTERKING45]

I'm past the point of no return, at the point where you get your gear and fight your way out, but every time I take the elevator to the upper hangar, the music goes out, and nothing proceeds the way it's supposed to.  The cutscene doesn't play, it doesn't tell me to rescue Mira, I can go back down the elevator, but it plays the cutscene again and I have to do the mission all over again, just to get stuck in the same mess again.  

 

It says my current objective is to Recharge the Pumps, and it leads me back outside but I can't interact with the machine it leads me to.  

 

Update: After doing everything I could think of to get the game unstuck, I had to start the game all over again and play through it again on hard and finally the cutscene triggered and I was able to finish it.
