same thing is occurring with me, right now i'm in the Newton mission where you have to rescue and escort 4 Reaver Elders to the exit grid, when i encountered the first elder, a bald chick, did the speech thing and went to get the nextone, however, he or she wasn't there, the dot that represents friendly characters was there, but you could not chat with the NPC because visually they were not there, maybe they were stuck in sneak limbo or something, did see security bots going for the alarms though maybe that causes them to go into sneak???, yet when i reloaded the mission i could not get the elder chick, someone out there hopefully can help, i don't want to wait for another patch, even though the first one doesn't seem to work properly, the game still crashes at the worst possible times, what with the "tough guy" feature on is really starting to piss me off
