Started playing COOP with a friend, this time the errors of yesterday seemed to be gone. We could play 3.1 en 3.2 en then AGAIN it became unplayable. Tried 6 times to play COOP Story at part 3.3 but after starting the level at random times we got the error 0006000021 and the game automatically disbanded.

This is so very frustrating. Since release there have been different errors everyday which make at least some part of this game unplayable. Sad that this is the reality these days with always-online games from AAA developers. If this keeps happening I'll stop playing altogether.
