I did the mission before I stumbled upon the Temple of Crota. The mission wasn't meant for you to go that way and I'm pretty sure it's a bug that it would lead you to the door of the Temple. There are pretty much two directions you can go after the first part of that mission - go to the right, not the left (towards the Temple). I'm pretty convinced that door is the entrance to a future Strike. This makes sense considering you can get to Devil Walker, and Sepiks door, from the Devil's Lair in free roam.

the temple of Crota is actually far from where the mission starts. its not the true temple where he lies

u need to have a bad juju.

I am having the exact same problem, cannot figure it out

i'm having the same issue. I am doing "Chamber of Night" and i cannot complete this quest because of the damn door not triggering. Bungie, this is a game breaking bug and it needs to be addressed. Also if its not a bug at least tell me what i am doing wrong. Pic related http://imgur.com/42nHXb2 #bungie #pissedoff #bug #wastingtimeisnotfun #story #templeofcrota #chamberofnight

For anyone experiencing this issue, it's because "Chambers of Night" start point is confusing. You spawn next to an entrance (acolyte+3 gardian) but it's not there the mission take place. First follow radar for the 2 cracks inspection. Then the radar looks like it point to entrance you just saw but follow it carefully; it shows the way to leave this map to the next, where the real entrance is (where you find the Exo talking and the dead guardian- small trail next to a big building, jumping steps, glowing door clip). I did same mistake twice... and the main problem is if you enter the wrong entrance, the radar don't tell you to get out but instead make you do a whole map to that blocked door :p
