I am currently having problems with the quest "I PUT A SPELL ON YOU" for the NCR.
(I apologize if this is how the quest is supposed to go but it seems unlikely.)

Basically what's happening is I have a save point right after I disarm the bomb on the monorail. It is greyed out on my quest list(completed) and tells me to go see Hsu is highlighted.

When I exit the monorail, the train leave and then exploads several second later. I check my quest journal and the note for it is not there after the train exploads.

When I go talk to Hsu it says the trains gone, even though I disarmed the bomb succesfully.

Ive reloaded several times, thinking there was a second bomb but I have found nothing.

I came to the assumption the the quest is bugged, if I am wrong I apologize.

While I dont want to just continue with the train gone, I will if necessary but I would prefer not to as I was planning on using it to get into Vegas if possible by having a high rep with NCR.

Please let me know if anyone else has experienced this problem or if I am just jumping to conclusion.

For now I will be either starting a new game(with this save still intact) or playing Gothic 4 until an update for this game comes out.

Thank you for your time,
