While replaying the quest "Death onto Dawn" using New Game+ and I got up to the point where you fight in Carteneau. The event is supposed to have save points throughout. However if you fail at any point while in New Game+, you are sent back to the start of the event. Meaning while in New Game+, you are unable to take advantage of the save points. I remember when I originally did this quest, the save points did work as intended.
