They won't stay at pushing the statue. If I take a break from them for even a second they wander off to wash their faces or be "unsure what to do."

And they don't breed as well, even with a fertility potion, as my nature tribe. I can't get the population to stay above 30. And most of the females are too old to breed now.

If I wasn't so close to finishing the last two puzzles I'd just give up.
