During the completion of the Lv45 Arc, the Corpse was bugged and did not work initially; progressing my mission without giving me the scroll — then locking me in chat until alt f4. Afterwards, it appeared the mission continued as it should — killing the 120 ??? Mobs; sealing the cave and such.
However, I have no extra dialogue options and after managing to ‘kill’ the corpse properly, I’m given 2 of the quest scrolls and Denkai continues to not give me the quest/quest dialogue.
