I can't find any other players in my game while playing Destiny. There is never anyone in the tower or during missions, and it won't let me play Crucible matches by myself. Everything is completely normal if I join the Fireteam of someone on my Friend's List though. I have looked through tons of settings, Googled it, posted on other boards, and no one seems to have any idea why this is happening. Is there anyone else with this problem? Or has anyone encountered this in the past?
