I started a MP game when my 18-hour clock had about 13 minutes left. The game lasted for more than that and I won. I got a brown chest as if it still was the chest for previous day, OK. But the timer had started to count down as if I had gotten the first win of the day. Although I didn't get that golden chest. So it should either award the first chest from new day or not start the new day's timer yet, right?
