This strike seems buggy regardless of it being a Nightfall. About a week ago I was running it just off the ROC list and I was down in the middle of the fight (one other player was up on the rocks... sissy) and we had to do the 1st wave 4 times. LOL.. yep, we'd finish the first wave (after activating the door) and nothing would happen but the radar was pointing to the door so I'd go over and activate with the "little light" ... we'd do the same wave again... and same thing... have to go activate the door again... 1st wave again. I think it might have been because a 3rd player was in the process of joining ... and it did finally progress once they were in but man...really annoying to have to play the same wave over and over.... talk about deja vu!
