This happened to me about 2 months ago. I was stubborn and thought it would eventually correct itself and it did! It took a month though... I accidentally did it again yesterday, so it will be another month before it"s back to normal. :(
My prediction threads:
Wii U will sell under 40m units (made on 14th September 2012)
PS Vita will sell under 20m units (made on 30th September 2012)
Wii U will sell under 7m in 2013 - I was right
