Mysterious Skin Appears

Alright, as I was loading into an ARAM game, I noticed my skin was not which I had selected nor was it one that I even owned. I figured, hey, maybe it's a bug and it'll be okay when I load in. But no, some how I magically owned the Celestine Soraka skin. I mean, before the ARAM game started, I didn't have it, I only had the Dryad Soraka skin. Somehow, between the game loading from the prep screen until we enter the game, I got a skin without any notification.

I'm not saying I'm complaining about having a magically appearing skin, but I just thought I best report it incase it's a frequent glitch.
