I was doing a one of the new task for the regattas, the one that requires you snowbording 1000 pies without losing (I'm playing in spanish languaje, so I don't know exactly what the sign says)

When the taks was finished, I've searched for the task icon to get back to the regatta task's window,and found that i've lost 90-100 green tickets. I didn't bought anything and nothing new is on my town, or in my storage.

Last time I've checked (this mornig), I had 103 green tickets, now I have only 7 tickets.
