We will be pushing a patch live tomorrow. Players will be returned to the title screen from their activities and then be required to log in to Destiny again after installing the patch.
Players are locked out of the throne room in Scourge of Winter mission.
Some players have reported that entering and then leaving the throne room in the Scourge of Winter mission will cause the door to close behind them preventing them from re-entering the throne room. If this happens to you, you will need to quit and restart the mission. This should take you back to the point where the throne room door opens.
