Sorry, poor wording, I meant adding the perk through the Auto-Doc. And there's a glitch that removes the trait dialogue from the Auto-Doc if you ask about it, even if you don't actually change your traits. Also, if you haven't turned on all the Sink AI, the dialogue won't appear. I'm sure you've long since turned on all the AI's, but I figured I should mention it just in case.
I still don't know how you could have lost Wild Wasteland to begin with, though.
