When you buy any Texture packs or any skin packs it tells you that you need to pay and everything then you play with that skin/texture pack you bought then maybe you close the game completely. then next day you open Minecraft PE then when you sign in to your Xbox Account then you want to choose the skin/texture pack you chose last time then i selected it then it tells you '' Purchase this Skin/Texture Pack To Use It'' but i already purchased it last time so this is a very terrible bug every time i need to waste 5 dollars every single time instead of i just buy it once.

THIS IS A TERRIBLE BUG FIX IT!
