URU: Tree Age-Pyramid Puzzle

Thank you for responding. We feared that our discovery might have
resulted from a programming bug, and so it sounds like from your
response our progress did result from a bug. Here's how we did it:

We discovered the tapestry in a nook on the outside wall of the
pyramid. So after that we explored the back outside wall of the
pyramid and we noticed what appeared to be a triangular indentation on
the back wall (base of triangle toward the top of the wall and apex of
triangle toward bottom of pyramid wall--forming an inverted triangle).
The indentation seemed like a key feature so we searched for a hot
spot. We walked along the base of the back wall, looking into the
illuminated ditch. We really aren't sure what the exact action was,
but after maneuvering along the back wall and looking in the ditch, we
must have made some effective action which allowed us to unexpectedly
fall through to the lower level. We had great difficulty repeating the
action again after we exited the game. We were able to drop to the
bottom level three times. On the third time, we touched the tapestry
on the lower level so were able to return to the lower level easily.
Since our progress appears to have resulted from a bug, we plan to
return to solving the hexagon puzzle in the floor inside the pyramid,
but we are struggling with that puzzle.
