Hello Narcc,
We're looking into this now and you will receive a refund in game for the 15
Printer Cases, 5
Optimum Cases and 5
Trash Boxes. We are sorry this issue occurred and are working on fixing the problems present, for the time being we will be disabling the prizes given out by the leaderboards until we can ensure it works properly in future.
Please contact a community owner in game to receive your refund.
