I have encountered two issues on werewolf island. If I do the siren quest, when I go back to talk to the leader the villagers do not turn against me and therefore I cannot get to the secret passageway to the ship. On the other hand, if I skip the siren part, everything works okay until I get to the ship and kill the leader. I am then supposed to click on the mast of the ship to go back to Ulgoth's Beard, but the game does nothing when I do so. What can I do?
