Was doing the Taimi and the Asura 3rd part of story line when I selected to use the Device to destroy the waypoints. After defeating the monter and talking . the last part was to follow Taimi but the robot never moved or star never went over his head.
I stayed for over 5 min when I left instance and started again. this time I select for the robot to use device and I defend. Finished the boss and there was the star above taimi head. Was able to complete this section of story line
