Well, I just lost both my healers -- they just disappeared from the game and the pop. count.
One was my elderly and sick Master Doctor, and I tried to use the Adept doc to heal her, but all they wanted to do was "Go Indoors" (This could be a great pickup line, you know.) The Adept Doc had just healed another elderly, so I know that he works.
I know the bug about trying to heal folks too close to the remains of others who have passed on before them, so I moved both the sick person and the healer to the other side of the well -- away from the remains.
Regardless of whether I dragged the sick person to the healer or vise versa, they either ran away or embraced. I made several attempts to heal her, but they were more interested in makeing babies, despite the fact that she was sick. (I know it's ok to have kids when your 65 in this game.)
The next message to come up (for my healer, while they were embracing) was "burying the dead". Then all the rest of the adults stopped doing whatever they were doing to come and bury the dead, and my healer and the sick person were "Disappeared", as they say in South American countries. They are not in the detail screens and longer, they are not buried with the rest of them.
The very least you can do is add a message that says "Aducted by aliens". The truth is out there, after all. . .
GRRRRRR!

Now I've got 5 adults and 6 small children, and a long way to go before I've got the points for L3 Harvesting.
I'm using a Palm T3 and the game is loaded to the device memory -- not the card.
Poo. Perhaps you could consider providing downloadable cheats, like Stella does for known bugs with Tomb Raider. These are saved games that get you back to a point in the game near to where you were before the game crashed.
