Forum:Arcade Gannon think I have "quite a menagerie" with me.

Coming to the end of my first play-through (Been taking it really slow and waiting for DLC) and have encountered a bug with Arcade Gannon. I want to start 'Auld Lang Syne' and get his ending but when I approach him with no companions he says "Quite the Menagerie" with me. When I approach him with a human/non mechanical follower he states "three is a crowd" as usual and if I approach him with either mechanical companion there is no option to recruit him at all. Please Help me out, my last save is before completing Honest Hearts I don't want to have to go back all the way, also I'm playing on xbox if that helps.
