With this package you are entitled to 1 stats reset on your account. To take advantage of this package, after purchase, you will have to open a ticket on http://discord.coralmc.it/ and manually request a stats reset.
You will have to indicate the Nickname on which you want the reset and attach the receipt that will be sent to you via email following the purchase of this package. It is not an immediate process and is not automatic, for this reason there may be an undefined waiting time before the stats reset is completed.
