Akali's Picture showing Gangplank's face(client)

I went on to my ranked team page a while ago and saw in our most played champions page, a visual glitch. The client showed Gangplank's face labeled as Akali. I could reproduce this glitch by playing a ranked game and going to our team page so some champion's faces Don't update yet... I would show you the screenshot but I don't know how to show it :/ ... This has happened occasionally
