Destiny servers are kicking people back to orbit, and some back to the login screen. Bungie is aware of the issues and is currently working on it.
Bungie posted the above reply saying that it’s currently investigating the cause of the issues, and is advising players to sign in again, though that didn’t work for me or the rest of my party.
Maybe I am just not destined to finish this damned Queen’s bounty.
