There's a bug where a campaign gets corrupted and is no longer joinable in co-op.
I've attached the point of corruption, a good save and the very next quicksave which is corrupted:

QuickSave_24 is loadable and co-op partner receives error `Joining failed: The session has no controllable characters available`. If I load a good save and have partner connect, and then load this save, partner sees "You were kicked" and I see "Player left".
