[SPOILER] HELP!!!! I have 1 stinking puzzle left

I have solved all the puzzles except the inlaid gong. I have an esteemed elder and totem. I have uncovered the mosiac ruins and I have placed the elder totem in the center of the ruins. Nothing is happening. I took the elder over there after placing the totem and nothing happened. I ahve reached all levels of tech. I have everything exactly like all the strategy guides say but nothing is happening. Can Anyone help? I am going crazy!!!!!!

Did you get your game from Reflexive? If so, see this topic.

If not, keep trying. You have to hit the exact middle of the mosaic. I've often needed several tries to find the right point.
