I've identified this as a problem with more folks than just myself so I'm not sure why it isn't being talked about more - the corrupted strike is BROKEN as in we cannot progress past the room with the orbs you use against the shielded phalanx early in the strike. It's the nightfall strike this week which is extra -blam!-. My last post didn't get any attention and this seems to be the only way to try to communicate to someone at Bungie that there is an activity prohibiting bug in this thing. I also need to do the "non-strike" mission version of this strike and last time I tried THAT was also bugged in the same exact way. Other friends of mine that play have had the same thing happen so it's not just a random issue with my game only.
