Points at 0

When I logged in to Listal just a minute ago, I noticed my rank was # 778, but I didn't have a single point. And when I last checked, I had somewhat around 3000 points (I don't remember). Is this a bug or what?

EDIT: Now when I checked, my points had returned. Still, I'm wondering what's the situation in here.

They will go to zero for a while when they are being regenerated.
