Please help GM, I've done Exam 10, I killed the Assassin's Bale, but then a pop up appeared, "You have failed the quest". I check the inventory, no change in certificate, still Assassin's 1st certificate. I've submitted a Ticket (Ticket IDL: 405011). I've tried to redownload and reinstall the Seal client, but nothing changes. Please help GM. Thank you.
