Why did the weekly game disappear when I logged on to FB?

I had to start all over again (from level 1800 odd) when I had to start a new Facebook page. I am now up to level 105. Before I logged on to Facebook I was playing a weekly game - there was only about 2 hours to go and I was on 96 and the nearest person was on 30 so I was easily going to win. I logged in to save the game and the weekly game disappeared? What happened??
