While on an expedition I was fighting a Testsucabra, and a Yian kut-ku comes out of nowhere. It runs off and I kill the Testu. I chase down the Yian and kill it, but while leaving another one comes after me. While fighting the second Yian, another Testu spawns. After I kill the secon Yian a great Jaggai spawns. When will it stop?!
