XBoxEU :
Completed the quest and assault last night - got the achievement, and was able to speak to Skordo. His quest marker (on top of his head) disappeared --- had a crash. I never got an update on the quest. Now both Skordo and the Azah is nowhere to be found. I have no quest markers AND the achievement is gone.
I have exited the game, restarted my xbox, reloaded the ui, every possible solution, and still nothing.
We spent HOURS working towards this, and then stuff like this happens - even asked in-game, but no one every responds anyway.
