Muramasa Momohime final stage problem.

[random90s]

On the last map in Yamato where you have to climb this tower to get to the last boss, I can't seem to drop back down when I climb the ladders. I head up and can't for the life of me get back down. This wouldn't be a problem if not for one part of the climb where I absolutely have to head down (outside the demon god thing chest). Loads of people have finished this game on dolphin so what's up with this? Help!
