Ottomas family

What's wrong with the Ottomas twins?
There is a known bug in the game that gives the twins a random father (and in some cases, a second biological mother) instead of listing Peter as the father. Their father is always a random Sim. It could be a Townie, an NPC (e.g. the Repo-man or Grim Reaper), a child, a woman, or even a pet. This has led some players to believe that Samantha is unfaithful.

For this reason, many players choose to delete the Ottomas family and make their own version. Another solution is editng the family tree with InSimenator. The twins are actually bugged, and a very bad thing for your neighborhood. Warning: could lead to a BFBVFS. The best thing to do is download InSimenator or the Sim Blender and terminate the pregnancy before the 'demon spawn' is born.
