We will be pushing a patch live tomorrow. Players will be required to log in to Destiny again after returning to the title screen to install the patch. You should not be removed from any activities you are currently in.
Hopefully in the story, or sidequest, or a dlc I don't care which we get to find out who built the exo. Maybe a counter force anpgainst the Vex? A weaponized ghost companion? Souls of those returned from the void?
