it seems that 1 out of 3 archive missions i do are bugged, either by disappearing npc's and i check 0, 0 , 0 in mara and nothing, or mission doors are stuck open and i cant get through em. also in the zion 4.2,1 mish every time it wants me to kill the friendly npc's that follow me i cant kill em, i have started the mission a bunch of times and the same crap happens, i get em and the objectives says it wants me to kill them, what am i supposed to kill em with....hopes and prayers.
