Disappearing half - price sale.

After playing for a while today, the half-price sale icon appeared but said it had been active for three hours. Hmmm... no way I missed seeing it for three hours. Also, the half price sale was available last weekend... usually there are two weeks between.

I left the game to check the forum and when I returned the icon was gone.

Just another bug :-/

So...4 hours later. ..it's baaack! ;-)
