It isn't a hack or an event quest. Once monsters are beaten at high-rank village, they can appear in the Moga Woods at night. I believe that the only monsters (that can be fought in the village) that can't appear in Moga Woods are Barioth+Sub, Agnaktor+Sub, Gigginox+Sub, Hapurubokka, Urcusis and Elder Dragons.
