I left my computer after I thought I turned off the game. Needless to say when I returned the next evening, I found that my computer hadn't "gone to sleep". Curiously I turned on the monitor and lo and behold (I always wanted to say that) the game was still running and it was on pause. The live mode was disabled.
Apparently my family died and the twins taken away. How? I have no clue. I thought they were on free will, but who knows. The tombstones were littered about the house (the parents were in the bedroom, one tombstone in the bathroom, the other tombstone in the other bedroom) and roaches were crawling about. So a bad case of the flu could have been to blame.
Thank goodness for exit without saving.
