A long time ago, I remember that after you saved Mitch in the downed AV you would scan some oil and tire tracks, and these ghostly holograms of jeeps would appear and you could follow them, first to a ruined air strip and then to the big gas station. But in my latest Playthrough those holograms never appeared and instead I just followed Panam. Is that something that was removed from the game on purpose or am I experiencing a bug?
