I'm experiencing a bug with 2 of the 3 decks

Hey AndreNeatz​, 

One of the items should be a grip tape, the white one with flowers. In your screenshot, it's called "Cor da lixa - Flores pretas e brancas."

The other deck you mentioned is missing; it could be above the current selection shown in your screenshot, since they're sorted by rarity.

Please check your inventory again, and if you're unable to find it, please send a screenshot showing all the purple-rarity decks you see.
