I was breeding one couple and the population count went up and they disappeard into the "love shack" she came out and I expected to see a baby - but there was none! I tried breeding them again - this time the count went up again and after she reappearing from the "love shack" she a one baby in hand. This happened to another couple also.(I thought maybe a twin glitch since I have not been lucky enough to have any this game) I keep a close count of my villagers (even who breeds with who - its like they are married-and the name of their offspring) and though the count is up I am two villagers short !! I did nothing to the computer after all the warning about the clock and those who timed warped I am extremely careful.

Thanks for letting me know the life span - I have read about villagers reaching 100 but I guess that is just luck. - I mistakenly thought they would live to be in their 80's after level 3 medicine

Tuna puzzler I am going to exit and restart the game to see if that helps but thes women already have another baby so we will see.
