Re: Karl and Woody in The Den,
No need to make these guys temporary NPCs and escort them back to their homes. Torr and Smiley won't even walk to the exit grid with you when you rescue them, neither does Krissy (or whatever her name is) at the Vault 15 village. It is strange that Karl and Woody will make it back to Modoc and Gecko before you get there in the car, but how to fix that other than adding some delay? = 'X days walking time between The Den and Modoc' If it was to be that realistic then they might not ever show up. (No idea how many times I was shot by robbers walking that path - well armed and NOT alone!)
Re: Gravedigging,
You shouldn't get the gravedigger status if that is just a stash and not really an actual grave. Depends on what the story is. (Which we don't know.) Did the Mordino's bury stuff in Golgotha and use a fake grave marker? Or, did they hide loot in the coffin of some unfortunate guy they rubbed out? A 'well-informed' gravedigger is still a gravedigger!
Re: The Car,
1. It stands to reason that you wouldn't be able to follow the raiders to their secret base using the car. Even with the lights off and using silent electric power, it would still make more noise and be more visible than walking. Is it more difficult to find the Raiders Base this way than it is to get the map from Bishop's safe? Is there an xp difference? I don't know.
2. Leaving the car behind doesn't make sense when rescuing Kurisu from the Slaver's Camp. If the slavers are all dead, then we should all be able to drive to the Tribe. Why can't she just run away by herself, whether the slavers are dead or not? Better yet, why couldn't the old script from the original Fallout be modified to work here? Tandi was in a very similar situation being held by raiders, and once you rescued her she would remain with the party until you returned to Shady Sands. Sulik wanted to get out and see the world away from the tribe, why not his sister? So she is worthless in combat as Tandi, Miria, and Davin, but we could visit the Primitive Tribe when we wanted to instead of being forced.
3. Leaving the car behind when getting help from the NCR rangers is really insane. I don't know how 6 can fit in that car to begin with, especially if you had Marcus and/or Skynet in the party. Certainly there would be no room for 2 rangers. No idea how to change this either, unless made to work in a "meet you there" way, like with Lara and the gang fight.
