mass effect- Where the eff is this keeper

Hey, I'm on my second play through of mass effect. I have 20 keepers and now I've come across a dilemma. this stupid keeper is gone. I've been on and off the citadel a bunch of times but it does no t seem to reappear

I think it's a glitch. I'm not sure.

whoa, never seen that happen before. The only keeper that I ever saw "not there" was the one in the embassy, before I even had the quest. But when I came back with the quest he was there.
 
Something tells me you are screwed... :(
 
Did you happen to talk to chorban and say "i'm done scanning for you" instead of "i'll keep scanning them" ?

Running on the disc or hard drive?

" There is a bug in one room that makes the keeper disappear.  You have to save and reload for it to come back. "

Damn its been a long time since I did that quest, although I dont think I had any problems with it and I completed that quest 3 times across my 5 playthroughs

Whoa, that's strange. I've never seen that happen before, but it's definitely a glitch.
