I have visited melody every day since the 1st. It was keeping track, but now it says 0/25 instead of 23/25. What is going on? Am I screwed out of the prize? I didn't see any othe topics about this issue.

Edit: It has seem to resolved itself.

Not everybody's was reset. Mine still says 22/25 (I missed a day).

That does sound like a nasty bug. I'd say file a ticket to see if they can reimburse you if needed.
