Over the past couple of days, every time I open Virtual Families 2 there's a dirt smudge in the same spot. I know the smudges happen, but this one keeps happening in the same place, and I have a maid but the spot still shows up. I make someone clean the spot but the next time I open the game (usually several hours later), it's back in the same spot. Other than that one spot, the maid is keeping things clean. I'm playing on a Kindle Fire and the game version is 1.5.2.0.
