the test tube baby should be a building that has a tick() method and thats where you put that Aging() method when age = 0 then the building is either destroyed or emptied then a pawn will spawn. then make a custom pawn class for the child and use the tick() method to put that aging() method again.
haha, it only has 20% chance of happening a day! you really are lucky, I think I should lower it to 10%.
thanks for that balance notes @oragepoilu!
