Bugs

 * There is a game-freezing glitch that may occur as you attempt to leave Zion through the Southern Passage after completing this mission. While walking towards the exit that will lead you back to the Mojave Wasteland, you may be approached by a random non-player character (many times a member of the Great Khans) and be handed a detonator. This will cause your HUD to disappear and your game to freeze. The only way to overcome this glitch is to restart your console.
 * Some Sorrows tribals may be left behind at the tunnel after the completion of this quest.
 * The game may crash when you detonate the explosives.
 * Walking along the river with Joshua Graham can cause him to get stuck in many places.
 * Sometimes the optional quests will not show up in one's Pip-Boy.
