Did the contests ended prematurely?
In the past, contests from both HH and CH ended at 6:00 AM (Central Time here) and a new contest starts 30 mins right after. Instead, tonight, it ended much earlier and a new contest will start much later which is weird. I don't know when exactly when the contest ended unexpectedly. Perhaps an hour and a half earlier than it did according to my screenshots... does the contests no longer takes 24 hours to compete? Maybe it was a glitch?
