Ok, I keep losing villagers suddenly. I've lost 3 so far of my original generation. They die between the ages of 50-55. I understand that's somewhat old for an early game stage, but there is no warning sign whatsoever. Their health is completely green, and then BAM they're dead. I don't leave my game alone for too long (at all) b/c I've become OCD about it, and as I've experienced with "sickness," it takes a little while to drain a Villager from full green to dead red. Is there something I'm missing? They have been master researchers and doctors who have died.

I'm at Level 2 on Harvesting, Science, and Spirituality, and level 1 on everything else. And I've had plenty of food (between 300-600) at the times of these deaths.

Boo hoo!
