i' m sorry if this is a repost, but this is very important. in the mission i put a spell on you there are multiple bugs. such as when you wait at night for the traitor to go to the control tower. every time you use a stealth boy (since i don't have a high sneak level) he doesn't talk on the radio. if you try getting closer to him even with a stealth boy activated he will notice you and attack you. the only option i had was to kill him. when you go to colonel Hsu and tell him about the traitor, he will tell you to check out the monorail. when you get to it the train seems to take off very fast. but i passed it by making a load point, so it was;t that big of a deal. the biggest problem was when you diffused the c4 using the codes or even using the science/demolition skill the train will still explode. i don't even feel like playing until they come out with a patch because i' m on a character that i want to be good and i don't want the train to explode when i diffused it.

The train exploding really doesn't matter much. You won't take a negative karma/rep hit for this. The only change is that some NPC's talk about the train exploding. Also, I believe I heard a couple saying that the train was repaired and the NCR is back in business. Weird bug to be sure.

ok, thanks for the info

Update:

Some NCR NPC's are still referring to the monorail being destroyed. However, I just turned on New Vegas Radio for the first time since I did this quest (about 15 gameplay hours ago) and Mr New Vegas just said the monorail was saved by an alert security officer.

:facepalm:

I just tested this, if curtis catches you when you are waiting for him he will try to kill you in the tower, i didnt let him catch me on my reverted save and he didnt catch me and i got the req for eavesdropping, now to do the monorail.

defused the bomb, didnt see it go and explode. damn if i didnt have a strategy guide i wouldnt have known waht the hell to do though.

My problem is I can't get conversation to trigger while I am eavesdropping. He just stands there, however I get the COMPLETED message for the task about investigating the radio tower. It is really annoying because I want to save the train.

I am pretty much in this same situation, i'm pretty much to the point where there is no way I am going to save the train.

For those of you that did save the train how did you do it? My glitch is that the game wont let me walk onto the train. The one time I did the train took off and I glitched through the walls of the train. I have heard that I can jump up on the rail next to the train and sneak next to the window. I cant do it while its set as my active quest (when Hsu sends me to check the train) it takes off too fast. But I read that you can get to the bomb if you do it outside of the quest. Either way I cant disarm the stupid thing! Any help?

My problem with the quest "I put a spell on you" is that after being told to check the tower for the traitor, i ran into curtis and talked to him, big mistake, now i cant even catch him going to the tower and cant progress the quest at all.... not sure what to do, last chance to get the "points" with boone to get his other quest, and im stuck. Any suggestions?

Don't know what that Boone quest is, but I encountered the same thing. But here's what happened after noticing I couldn't advance... for now. I went to do other missions. Came back & not only was Curtis not there anymore, he doesn't show up anymore. At all. UGH!!!! Even if the arrow keeps blinking, nothing happens. So tired of this issue. I'm also tired that the East Pump Station won't show up as discovered.

it does matter for people who dont use fast travel. youve got a lot more to walk if the train is destroyed.

My understanding is that if you hear the conversation and run straight to the train you can successfully disarm it. Can't verify it personally, however. Curtis noticed me immediately upon entering the building (with silent running and no line of sight...) He gave up looking for me on the stairwell and just sat there, so I killed him and returned to Hsu. At this point, Hsu gets suspicious and tells you to check out the monorail. I think the monorail is supposed to take off as soon as you enter the area if you talk to Hsu first. The problem is that sometimes it doesn't trigger right away. I had saved right before I entered, so I tried this several times and could find no rhyme or reason to it. Sometimes you hear the "train departing" message as soon as the area loads. If you don't hear it, and you can manage enter the tram you can deactivate the bomb (to no effect, though it falsely triggers a successful quest marker) and it won't depart until you leave the tram. At this point it should depart immediately, as it should have to begin with. Hope that is helpful in solving this little mystery. The upside is, of course, that you can still finish the quest, and the tram wasn't packed full of orphans or puppy dogs, so all's well that ends well.

There's a corner you can walk into (I think to the left of the entrance), which will trigger the discovery of the East Pump Station. If it doesn't, just walk around the building while rubbing against the walls... there's a 'sweet spot' somewhere. It worked for me.
