We are actively investigating issues impacting players' ability to sign in to Destiny on all platforms. Until resolved, players may experience disconnects or be unable to sign in.
Occasionally, the HUD would dissapear for unknown reasons. This forced the player to restart the game because you could not summon your Ghost. (Sometimes you would have to restart your console) which was quite inconvenient when you enter a Crucible for Strike to find you have to leave your team because of HUD issues. Just throwing it out there for Bungie! Great game otherwise!
