Free Skin

When i played as veigar in the new draft pick (normal) it let me use white mage veigar, but the skinw asnt selected. i though "oh i didnt know i had that skin", then later i tried to use the same skin, i dont actually own it. i have been trying to recreate this bug so i can say how i did it, but i hvae had no luck. all i remember was scrolling through his skins, and stopping on white mage, then boom i had it in game. sorry i couldnt give you more info, but if you go through my veigar games youll see (if you can even check that) that i had a skin on, and others could see it too (i asked frineds on skype). Hope it helps!!
