Free chroma skin? (1-game only)

Alright, I guess I have a bug to report? Me and a friend of mine (The Diamond Hero) were using the new champ select for Normal Draft mode, and I selected Darius and they selected Caitlyn and we switched when the time came (we didn't want a first pick adc). I selected Safari Caitlyn for my skin and The Diamond Hero used Darius' normal skin. When the loading screen came it had given me the green cait skin from the chroma pack and it gave The Diamond Hero the Darius Forge skin (bronze one). The skins remained throughout the game, but once the game ended neither of us had the chroma skins anymore. I figured Riot should know there is a way to exploit the new Champ Select to get a (most likely) random chroma skin for their champ. P.S. - I really like this new champ select guys, good work [slayer-pantheon-thumbs]
