In "Cold Hand Warm Heart" (September 2024) Kirito defeats the 58th floor field boss, but by "A Murder Case In The Area" (April 2024) it is mentioned that the frontlines are already at the 59th floor. Since the field bosses can only be killed once and you need to defeat them to enter the Labyrinth, how can this be possible?
