There need to be a chance that the seer's random scan hits the dummy. Unless the scan the seer got night 0 had a chance to hit the dummy, but given Bearth was hunted I doubt that.OOC: Would giving the seer another randomised scan next night be a solution?
So yeah the seer needs to get a random scan which had a 1/15 chance of hitting any person, including the dummy. So 1/15 chance of hitting the dummy and 14/15 chance of getting an actual player.
The wolves then would hunt the dummy. As the hunt night 0 seems to have also had a chance to hit the seer then there shodln't be any problems there. Plus even if it didn't there isn't really a way to fix that.
So yeah, night 1 the wolves hunt the dummy and the seer gets a random scan with a 1/15 chance of the random scan being on the dummy.
