The first time I try to load into any portion of the campaign in a session (aside from the Battle Barge sections), the loading icon in the bottom right of the screen will suddenly say 'DISCONNECTED' and kick me back to the Battle Barge saying 'You have failed to connect to the game'. I also get this 'DISCONNECTED' issue every time there is a loading screen within a mission in the game - it kicks me to the Battle Barge and I have to try again. This typically happens once, but sometimes it has locked me out of being able to play the single player at all.
This is an obscene issue. I'm trying to play single player, on my own, with nobody else. Why is there any issue with connectivity at all? It should all be happening locally, there's no need for any online connection at all (unless it's designed that way which is inherently anti-consumer).
