So I'm trying to work out how to solve the puzzle in Selunes temple (the one with the spinning disks). When I first came across it, it worked fine but now some of the moon sections are overlapping and not swapping from disk to disk like they're supposed to, leaving blank corners and effectively making the puzzle unsolvable. Is there a way to fix this? And if not, is this actually the only way into the underdark or is there another that I'm missing?
