So I've completed Still in the Dark, and Eyesight to the Blind and McNamara is in power. He said he would lift the lockdown and on Radio New Vegas they said something about "dark figures moving about Hidden Valley after dark." But I haven't seen any of the Brotherhood patrolling the Mojave at all.
Also whenever I ask Elder McNamara about the lockdown, he tells me about it as if it were still in effect and shows no signs that it has been lifted.
Do they actually go out on patrols throughout the wasteland?
