No, but I did notice the Maxis families that came with pets are still there, though no on knows them.  Could they cause this?

Nope, it's a recently made custom hood.

Recently, my toddlers in a neighborhood have been getting Lifetime Wants and romance sims have been wanting to marry of 6 kids.  I realize my 'hood is now corrupted, but I don't know why this happened.  I have not downloaded or used any occupied lots, and I have never deleted a sim from it.  I have the director's cut, but no other CC.  What am I doing wrong to cause this?
