After sitting there for about 5 minutes it suddenly loaded all my missions and stuff but I was still stuck, then the server dropped me.
I played for a few hours earlier but it did start to degrade before I logged out about 90 mins ago. I got disconnected transferring into a random cluster mission and couldn't log back in for 10 minutes. That was a big bug at the end of OB but I thought they had squashed it. Apparently not entirely.
