I just completed the 3 challenges with my raid group and the game glitches and froze on us. We went back to orbit and reentered the raid, skipped to Calus, and beat it. Me and one other in my raid group had no keys when we went back to the tower. WTH? I just spent 2-3 hours of a weekday evening completing this and now I'm being cheated out of exotic and powerful gear? I shouldn't have to read the damn Help forums to know I should have logged in to my warlock first before completing the raid on my titan. That's BS.
