Just a few I wanted to throw out/remind before patch release.

1) I activated Alternate Quest for I Pu A Spell On You and retrieved the explosives from the garbage. I decided to finish it with the NCR route, so I went to disarm the monorail. The menu clearly displays the two deactivation options, either science or using the code. However, neither one works. RIght after I select one, the msg pops up confirming the disarm, the quest updates, and then the quest item appears AGAIN with empty box to disarm train. Train takes off and blows up. No matter what I do, no matter the route of eavesdropiing or killing, the game blows up the train. WHen I return to HSU, it gives me the dialog "I blew up the monorail" as if I had actually planted the explosives. My conclusion is that once the explosives are in inventory, you are unable to complete the game on the NCR path. Even though the prompts say "deactivate" they actually plant the explosives instead... OR it does deactivate and then ALSO plants the explosives due to some poor programming.
a) Note that after I picked up explosives from can, that quest objective cleared, but then uncleared, so clearly the whole alternate quest code here is bum.

2) Still unable to help DOc fix up his three troopers at Forlorn. Option exists to click A to diagnose, but nothing happens. This may be because I clicked on each trooper before quest when the option exists to inspect them, and the msg pops up stating that there is nothing I can do or talk to the doc or something like that.

3) Unable to get into inerior rooms in the U3 tain tunnel outside boomers base. WHen I walk into doorway and up stairs, I fall into space. The terrain mesh drops off to oblivion and the floor and steps are non barrier.

4) Unable to complete RAUL Ghoul Free Quest if I get him after I have already dialogged with the three relevant people. Those dialog options are gone in subsequent conversations and speaking to them does not get RAUL to speak at all.

5) Trying to activate RAUL's repair feature in his shack gets the same sarcastic response as outside. I am unable to get him to do anything with the repair dialog option.

6) No reputation on World Map for Nelson, even though they attack me. The Rep here is clearly local, but doesnt display. I am liked by Caesar everywhere else, this is only place that attacks after I freed the hostages (using stealth).

4 - Definitely still a bug, yes, it can't be done if you've interacted with certain people earlier for some reason (which seems strange they'd do that since it'd be very unlikely you would meet Raul before you would meet Andy, at least if you're mostly following the quest, not sure who would voluntarily fight that many Super Mutants at such a low level but... hey, to each their own).

5 - I don't think this is really a "bug", moreso that he just won't repair anything while he's a companion (no matter where you are). Unless you mean you DON'T have him as a companion in his shack? If you do, go to the shack and tell him you want to part ways. He would go to the Shack anyway, so since he's already there, just ask him about repairing. Shouldn't be a problem (again, unless that's the bug you're talking about).

6 - They attack only AFTER you free the hostages? But not before right? It's possible even with the Stealth Boy (which isn't perfect) you're still being seen (remember as well, certain things such as the dogs, and specific types from each faction can see through all costumes, and the Stealth Boy isn't a be-all-end-all in this game, maybe THAT'S a glitch, I don't know), this is kind of a "no matter what" quest. If you do anything to those NCR slaves, Caesar's boys will be pissed. You can only complete this quest by being an NCR loyalist, or POSSIBLY by being praised by the Legion so that you'll only end up as a Dark Hero to them. OR maybe by picking them off in sneak from really far away so they don't see you (either the Legion or the NCR guys, since you can technically complete the quest by killing them and sparing them the pain, but that also pisses off the Legion and they will attack you) I don't think this is a glitch though. The Legion doesn't want them dead yet, and they certainly don't want them freed, they want them to suffer, even if you were the Legate himself, you can't touch them.
