I hadn't played this sim in awhile so I don't know whats going on here, my sim has mopped up twice and the puddle in the bathroom next to a window keeps growing. Does anyone know what in the world is ...
Don't know if this will help, but I had a random puddle that would show up in the middle of the room for no apparent reason, and I finally figured out it was the toddler potty overflowing...weird that the puddle showed up nowhere near the potty, but that was it!
