I don't know if the two things are related, but....

My Powers were broken right after I over-Bloomed the Noni bush. I had something like 1020 Noni, which then turned into 900-something. Then when I tried to use any of the powers, nothing happened. I would get the sound of butterflies or bees, but no actual butterflies or bees spawned and villagers did not react.

Switching to another tribe and then returning fixed everything, so it's not a big deal, just a small bug, I guess.
