I have never had that "event" but I think it is relevant if your villager was an elder , then you would get a clone elder , hence some people with 53, 52, 51 elders, only an event like that would do that
I will stand corrected if I am wrong
I have had mostly sack events,,, I know nothing exciting, each day I await , new villagers , but no , another darn sack!! lol
although I did get a barrel of babies , well one small child, that is the most exciting my events have been , even ringing the gong... gong granted youth , all stayed the same, and i could tell by their ability levels and there was no change!!
