Mhmm the chinese wiki has this on their website:
February 15, 2011 February 16, 2011 "Shen Ji" sweepstakes God appeared 3 times!
You sure the Good sweepstakes are on Sunday and not on the 15th, AFTER the light event ends? (yes, that's google translate, I don't speak chinese.)
The FB group rolled forward a day and it activates. It's a 24 Hour event.
The Shrine dungeon supposedly shows up 3 times and it's the same King Gold Dragon, but you get a stone for all 3 times you do it.
