I fought for both NML and MB. When fighting for MB, I would lose all my AP when still on friendly territory, but then when I entered NML, the Underground, I was able to move more freely. And I would lose whatever AP I had, whether it was 70 or 140. But the same was true for when I carried for NML (from the Underground)
Also, can MDA be included in the Torch fun too, please! Perhaps the Captial could be the Indexed Room of Memories, the Great Hall of the Sun or just the front entrance of the building.
