Black Alistar Skin problem in ARAM matchmade

Hy! Am i the only one who encounters loading game problem with black alistar skin in any aram matchmade ? The problem is like this and i encountered twice. 1. Go to aram matchmade. 2. Be sure you have alistar as a champ. 3. Receive or purchase skin boost and select Black Alistar. 4. Wait. The problem is that if you follow the steps you won't go in the looby to load the game.. you will remain only with client sayng Game still in progress. Also at you status says that you're playing the game. If anyone encountered the bug please confirm.
