I adopted a child and got the same child (same name, same looks and only 1 child visible on the family tree) twice. So now I have the adopted child and its clone running around the house.

Also, my lawn is unchanged (constantly brown) ever since I bought it, no matter how often I sprinkle the water over it.

Another thing missing is a collectibles screen for ornaments. I am getting ornaments, but there's no collectibles screen for them and if I pick the same one more than once I can't sell it, it always counts as a new one.
