Having finished all the puzzles etc Like VV1 I just leave it running and look in on it from time to time.. Just looked at mine today after a couple days and after previously having had a dramatic drop in population Im now back up to full capacity and I discovered I have 42 11 yr olds. They are the product of 27 mothers and only 9 fathers, one of which had 19 of them! Three of the women had three a piece and they definately werent all triplets. EG Bes's three are a set of twin girls with long mousey hair and a girl with long black hair! Bibi's 3 are a set of twin boys with red hair and a blonde girl.
