I am also experiencing this issue. After I dismissed the dialog about the golden child, all my villagers started worshipping. I was able to view the child's details (all stats at max, 5 years old).

EDIT: After looking at another thread, it's important to note that I DID drag the golden child to the boulder. This caused him to disappear.

I've looked through all of my villagers' detail screens, and he is not there.

For reference, I have 10 of the 12 puzzles solved, and I'm playing on a Treo 650.
