Etokas Cho

Etokas Cho is the deceased husband of Vivian Cho and the father of her daughter, Etsu Cho. He is dead before the beginning of The Sims 2. His family tree is peculiar. It shows that he adopted his parents and grandparents but they had him. He is featured three times: once at the top and twice on the bottom row. On his tree, it seems Vivian and Etsu don't exist.

A similiar thing happens with Leandra Rutherford of Belladonna Cove.

These problems come The Sims 2:Apartment Life.
