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.
There is no quest marker for "The Court of Oryx" Quest
Bungie is aware of an issue where the Quest marker for starting "The Court of Oryx" Quest is not visible. This Quest can be accessed by speaking to Eris Morn in the Tower after participating in any Court of Oryx victory on any tier.
