I believe that the dancing on the minefield mission where you have to drive a vehicle that's surrounded by mines in the desert is bugged so bad it breaks the rest of the game. After a few hours I noticed when I rarely died that Johnny would keep saying the same line over and over again from the mission I listed above when loading back in. Not thinking much of it I continued, where now 8 hours past the completion of the quest, I can't talk to johnny or progress with any quests involving him. I just wanted to put this out there to try and get it resolved. Hopefully this gets fixed soon. The other bugs and glitches are manageable, but not being able to continue with missions is just frustrating.
