On the Xbox version of the game, one of my Characters is stuck in The Martyr: Chapter 2 ("Talk to Omicron Arkh" after collecting the tarot).

I've rescued Omicron Arkh and had him on the Bridge for a while, but a couple of missions ago, he disappeared. I need to speak to him to progress Chapter 2 but can't continue.

I cannot progress the story and am reluctant to delete my character. I've tried signing out and in with no luck.

Xbox Gamertag: Fighting41st

Character: Garviel (Crusader heavy gunner)

I know that I should have omicron at this point as another character of mine has reached this point and has him.

Any help would be greatly appreciated.
