I have a little problem, while my friend is involved in Co-op-dialogues: I can't read his answers when he speaks or asks someone and I can't read his answer, when we have an discussion.
For example the body at the beach: He agreed with me, but I only know that, because I have played this dialogue already three times and know that you get one point pragmatism, but what he directly said I couldn't tell.
I just read "waiting for other Players" and then the Co-op-Dialogue is over.
