Okay, so my little sister made a family, which was Mom (adult), Dad (adult), Daughter (teen),and Son (teen). When Daughter became a Young Adult, She kicked Mom, Dad, and Son out of the house. So, skip about a week. She is having a wedding party, and invites Mom, Dad, and Son, (And Son 2 (New kid)). MOM SHOWS UP AS A FLOATING HEAD WITH FEET! She hobbles around everywhere as an elder, and her body is invisible. It doesn't seem to bother the sims, but it freaks me out! Weeks later, her body reappeared.
WHAT IS GOING ON?!
