I've yet to find a specific answer to this question. When I ring the Gong of Wonder a random message displays. For example it'll say; "Gong of Wonder takes Technology or Health". I've done this 3 times and noticed that when it takes health, more of my villagers die. I thought the Gong was supposed to be good thing.

I have all of the puzzles solved, Level 3 in all technologies. The only collection that I've yet to complete is the Beetles and I'm only lacking one. Could that be causing my Gong to have negative effects or is it something else?
