The players don't understand that the execution provides information; that in a normal situation, there would be three deaths per night plus a No Night Victory (NNV), but here there are zero deaths and decent probabilities, even considering the raw statistics for the roles – half of them are negative, and you can also read the posts about the suspects; that the Seer is dead. They think that since there are no murders, they can relax and just sit around, and many don't even read the thread.
