Well, honestly, I'm not sure if he went missing while the game was paused or shortly after I started it back up. I noticed the population number after maybe 3-4 minutes of restarting the game.
When I pause, I typically hit the space bar and usually just leave the game running but that particular time, I went ahead and exited the game.
Chances are, he'd died and got lost in the shuffle.

He was about the age of the other's who'd already passed.
D'ya think maybe our missing villagers have been abducted by aliens or maybe found their way back to the other villages? Maybe they've simply reached a higher plane of existance.

Thanks for your help.
