I left my game on 1/2 speed for a couple days and when I came back something really weird happened.

Earlier in the game, I had the "babies in the barrel" event and given the family name "Barrel" to those 2 kids.

Now I just looked at all my villagers (general check of everyone) and one of the two Barrel boys has duplicated! I have the exact same guy with the same name, age, skill (but without a check mark) and outfit!

Anyone else ever had that happen before?
