Killing a sister and I ended up back outside the ship unable to complete the mission

[souldead341]

Solo killing my latest Sister of Parvos and I finished the fight, converting her.  Immediately after the convert cutscene I was back outside the corpus ship in archwing.   Near as I can tell the cutscene was completely within the level, not dropping me outside the walls of the level or anything (even when that's happened to me before  was fine and back in the level anyway).

I was able to enter the railjack, but unable to re-enter the corpus pylon. 

Mission objectives were still to reach extraction and enter the railjack.  Unfortunately because I wasn't able to reach the "proper" extraction point of the pylon the mission wouldn't end and I'm now forced to redo it.
