Hello

I was playing Crysis 3 on my xbox 360 and came across to an odd problem, bug you might say. After the cutscene where mastermind draggs off prophet from the VTOL, and prophet escapes behind that stone wall and I start playing, there is no mastermind to destroy.

in this video at the same spot (4:00) when game commences, I have nobody else on the building roof, just myself. And by the looks of this video, mastermind should be there without doing anything what would trigger him to come.

Help?
