Did you PS3 owners get a chance to see if they fixed the airlock glitch?
I just finished playing through this on PS3. There was one time where an airlock took a long time to open, and a few other times it took a little longer than you'd expect, but I just figured it was a hidden loading screen (why else would some doors require a button press and others not, when they're otherwise identical?). I didn't come across any glitches, or any OTHER glitches, if that's the door glitch. But it just made me stand in the room for like a minute or two, no big deal.
