So the part where you go to a squatter camp in Freeside and the NCR guy gives you the quiz to see if you're a member, the last question is "what is the mascot on the NCR flag?" With every answer, he says I'm wrong. This wasn't a problem when I did the quest before, but now it is. Anyone else having this issue?

Just to give you a reply. This is unknown to me. Guess I did the quest in another way (after carefully reading the wiki) not having to involve the squatter camp.
