Just got to the waterfall puzzle and was having a hard time trying to figure it out. Found some handy guides online, which are very good by the way, and followed them exactly. Everytime I completed the puzzle it keeps saying "The waterfalls seem to have reset themselves". Tried again. Getting the same error.
I also got the map from http://www.gamefaqs.com/console/ps2/file/459841/46240.
Waterfall Puzzle Path 1 - http://tinyurl.com/y7rkwy
Waterfall Puzzle Path 2 - http://tinyurl.com/t4xqt
URLs provided gave a map which corresponds to all other guides and they all follow the same path.
Is it possible I am taking the wrong path somewhere?
