I know this has already been talked about but it really needs a fix, not only when my fireteam did the raid did Calus not appear after a wipe, forcing us to go to Orbit and come back, but on our second damage phase we took out his health on the last plate. Then we took out a quarter of his final shield before he went immune and wiped all of us. We should have completed the raid and gotten our rewards, instead we had two guys leave and we couldn't complete it with the two new people we picked up. Bungie takes the time to delay the prestigious raid because of a glitch, but they haven't even fixed a glitch in the normal raid that's been happening for weeks now. It's ruining players experiences and makes people not want to play the raid because there's so many glitches involved with Calus.
