While playing I found the maps for the locations of the Lighters, Baseball cards, Cheesburger bobbleheads, and Records.
But I sadly found out that these maps all seem to fail to identify one of the items for the sets, making the maps completely worthless as they pretty much force us to fall back on player-created maps that list all of the locations and have to check out every single location all over again.
So I'm wondering... why even make these incomplete maps available in game?
