Last night, I completed the "Lost to Light" mission on Destiny The Taken King. During the final "End of Mission" sequence on completion, I saw red banners at the bottom of the screen informing me of connection issues to Destiny servers. When I then exited the mission using "Go to Orbit", I saw the mission was incomplete on the map and I was unable to view my postgame stats. When I logged back in this morning, the mission was grayed out and inaccessible on the map, as if I had never unlocked it. However, I am still able to progress in "The Taken King" quest line, and the objective in that quest line is fulfilled. I am not sure I ever got rewards for this, but more worrisome is that I am now completely unable to access that mission. Is there any way to re-access it? Is this a bug? Thanks!
