I am currently playing the quest "Chamber of Night" on the moon. It's a level 8 or so story mission. Anyway, I left the mission before I completed it the first time. This was once I was in the "Respawning Restricted" zone. I went to go back and complete it later and I could continue by pressing X or restart the mission by pressing |_|. I decided to restart but now when I get to the "RR" zone it doesn't trigger and enemies don't spawn and doors don't open. So now I am stuck in the story because I can't get the instance to trigger. Anyone else having this problem? Bungie can you help me out? I'm playing it on PS3
