At Camp McCarran at the end of the "I put a spell on you" quest when u talk to C. Hsu and he tells to get to the monorail to defuse a bomb 80% of the time the train just takes off as soon as u open the door and step out onto the platform and explodes around the corner. 20% of the time u actually get on the train and defuse and remove the bomb but as soon as u step off the train it takes off and blows up anyway! Even if u get to the door before it blows u still end up telling C. Hsu it was destroyed. Oddly enough this is the only problem I've really had other than 2 freezes and minor bugs in 19 hours of play.

I think theres a timer as soon as you eavesdrop on the convo since i managed to defuse the bomb.

This is definitely a glitch, here is the deal. You have to sneak and eavesdrop on the conversation then go and defuse the bomb. If you kill the spy before you here the part about the bomb, and the quest is updated, then it will explode regardless. Even if you make it to the train and defuse it (which I did, using Turbo) it will still explode if you don't eavesdrop on the conversation first. It's a really annoying glitch, that should have been caught during play testing.

I had the same issue, I diffused the bomb, but the monorail still blew up. The weird thing is that NPC's talk about it being destroyed, but Mr. New Vegas talks about how it was saved by an alert security officer.

In the quest after talking to hsu, I entered the tower and the spy met me right at the entrance, entered dialog and i had to kill him. I went to hsu and told him who it was, he told me to hurry to defuse the bomb, which i didn't know there was, because I didn't hear the conversation over the radio. When I reached the monorail, the train took off and exploded. I thought...ok the quest is over. But now I am in the quest "No, Not Much" and I need to get Hsu to send troops to Bitter Spriogs. My rep is accepted, and I have completed all of his tasks, the interrogation, and the other tasks around the base, but he still refuses to send troops. Is all this because I didn't listen to the radio conversation?

Having another quest break because of another one is annoying :facepalm:

I have similar things like that with my companions, talking about certain individuals as if they never met them, even though they helped me kill them 15 minutes ago :facepalm:



(Fallout 3 has a major fail like this when i heard Three Dog speaking about how the Brotherhood of Steel fixed the purifier and made the water clean again... even though i didnt even do that quest yet :facepalm: :facepalm: :facepalm: :facepalm: )
