I did manage to get back in after waiting for 'Account already logged in' to clear but I missed most of the fight. I thought the Undaunted Celebration had been delayed to ensure stability. Can this be fixed?

(I also had over 20 freezes during the Cliffs of Failure mission a couple of days ago.)

EDIT: I just did the veteran pledge on my original/primary account without issue. Now I think about it, I think all my freezing is coming on the secondary account. I could be wrong but I got the impression that the new client removed the need to occasionally delete the save file. I have cold-booted my Xbox and reinstalled the game but would deleting the save file for my secondary account do anything? Hopefully someone (e.g. @ZOS_BillE ) can advise?
