This seems very much like the track renew bug from the Egg Hunt last year. And from other similar events.
Basically, once the clock ticks down to the point of renewing the tracks it'll just stay locked and reset the clock at 6 hours again...
Another sloppy issue that drains diamonds from players.
Here, after opening the game and going to the World Map.
