Hi. I have the same problem. At about 23:30 I spent over 250M money (2 contests in Activities + Great Pachinko) but after reset I got reward from being placed at 3800th+ place. Before spending those 250M money, I had already 51M money spent so in the end I had over 300M money spent which should place me at 70th-80th position. Unfortunately I didnt take screen shot of rewards, but I have screen shots of my Contests at that time.
Immidiately after reset I wrote ticket to Support, but after 17 hours noone answered me.
Please, fix that problem.
