i just imported a character from a playthrough and everything is fine in the beginning up until i get to the part where i have to pich up the grenade launcher. It tells me to push A to pick it up but, when i do, it doesnt prompt the group of mechs to come through the door. it basically strands me up on the little balcony because without killing the mechs and exploding the pipe it wont unlock the door to take the elevator down.
any advice or input would be much appreciated.

P.S. I've imported other guys from different ME2 careers and they seem to work. the only thing i can think of that makes this guy different is that i completed overlord before completig the final mission and importing. the other guys dont have that about them
