I know this is 5 years old, but, I followed the walkthrough to a T as well, and saw quite a few errors, mostly during the parts with the stage and watching the terminator physically move the bomb (that shit just never happened for me), it all worked out in the end but I kind of had to wing it despite the wrong information in the walkthrough. The missing fun point was ripping janices shirt off, i know exactly when it was supposed to happen, i reloaded a few times to figure out why it wasn't showing up, and it just never did, and im not really sure what the trigger was for it. Guess the best thing I can hope for is to just redo that entire section and hope for the best?
