Bad news. After level 3 was completed, I sorted which ones I wanted to sell and clicked to sell them. The sales screen opened and I got a glimpse of the crowd moving to the door...think it showed that one sold even before anyone even got through the door, but not positive cause the game closed up so fast.

I then shut off my Nook, did a soft reboot (hold the power button for 20 - 25 seconds) then turned it back on and opened the game. I had to resort which ones to sell again, but this time it didn't close on me and they all sold. Afterwards, I chose which ones to get pregnant then went into Options to put on 1/2 time and closed the game.

Oh, but I now have over $10,000 so that didn't trigger it.

I'll see what happens when I try to sell again. One thing I have realized though, I can actually play just fine as long as I don't ever buy level three of advertising.
