Reset Sand Ranges 0 / reinicio rangos en arena a 0

After the upgrade completed a few days ago, all ranks have disappeared obtained in sand, in which were several levels range Onyx, diamond, gold and silver and all changed to zero.

What is this about? There is a way to recover all the information obtained above ranges to avoid having to start over from scratch?
I thank them all the information and help you can give me.

A que se debe esto? existe una forma de recuperar toda la información de los rangos obtenidos anteriormente para no tener que comenzar todo de cero?
Les agradezco toda la información y ayuda que puedan brindarme.
