I have been playing co-op with the same person for the entire campaign (she hosted), and neither one of us played a campaign mission in single player. Together we unlocked Death From Above, Buff, and Force Field, and I used them for a little bit in that co-op game. This was all pre-patch. When I load my save into single player post-patch, Death From Above, Buff, and Force Field no longer appear in my Powers menu (and in perhaps a related vein, Gat no longer appears on the ship). The cheat to activate and give all powers does not make them available. This lack of availability occurs in all of my saves, even ones near the beginning of the game (right after entering the open world simulation for the first time--the cheat still doesn't work). Does anyone else have this issue?
