Hello again Edge.

I have a question. It turns out that my players complain about sometimes can buy a store sign, which is added to another group and is repeated the purchase.

In this picture you can see that the player purchased be added to a "Yunque" group and below the "[player] tu pedido en la tienda ha sido dispuesto" twice. For some reason, perhaps by lag. But several times buy the same and that lessens their many points.

Is there any way that can only be purchased once being added to a group of permissions?.

Sorry for my english ;)

This was corrected in V2.0.0
