I am running 5 tribes and all seem to be working well but one. The chief refuses to make food and they need it! It only started 3 days ago and I try everyday and he refuses.

Maybe he's on strike

That's weird. I have 5 tribes too and have never had a chief refuse to make food or do any of his other jobs unless it was less than 24 hours since the last time he did it. Maybe you should ask tech support?

I had that issue with teaching children once; very strange, but it just vanished after a while. I can't help you with this one.

That's strange! unless it's because he/she is under 14yrs old. I don't think that should make a difference though. Good luck anyway.

It shouldn't with food.

Does he shake his head, and say, Refusing? Or does he just not do anything.

He's an adult and he refuses but he did finally did it today! Maybe it was just a small glich.
