You missed 12-14 puzzles by using that save (nearly the entire Mayan world), and you also didn't get some important clues you need to make sense of things. If you like, I can type out step-by-step directions from the strategy guide that should get you through the calendar puzzle, but they're too lengthy to post here. Please contact me via GB email if you'd like the directions. Also, let me know if you have activated the metamorphosis god with the crystal globe by solving the Mayan number puzzle. If so, I'll start my directions from there.
Edit: Gemma, see your email.
I acted my age once. It was boring.
