I've ran into a problem that I have encountered once before. If the Daily Heroic mission lands on The Shrine of Oryx mission, I get to just before the end and the objective will cease to update. In the room with the Ogre (it's like a hallway that leads to the shrine) the objective is to delve deeper into the shrine. Once all the enemies are dealt with and I move on into the final chamber, the objective will not change and will not allow me to scan the shrine to start the boss battle to end the mission. I'm not sure why this happens, but I had it happen just now and once before towards the beginning of the Rise of Iron. I wanted to bring this to light so that it may hopefully be patched while I'm grinding out the new daily story playlist. I love that part of the update!! I'm looking forward to the rest of the Age of Triumph!
