I'm pretty sure no doors are scripted to the robot's death. I've blown right through that section without even bothering to engage the robot. I also tracked down the dialogue file. I was right, I'd missed an open bracket. It was a female-specific line, so it might have only crashed the game for female characters. I've attached the new file here, and it'll be included in the full New Reno list I send to Dionis when it's finally complete.
