I'm experiencing a problem with the opening cutscene of mission four. The first few playthroughs the cutscene of the viper launching played as it should. Many playthroughs later the camera seemed to get lower and lower. Now the poor cameraman is smashing through the rungs of the launch tube. What could possibly be going on here?

Here's a video of it...
