[Gameplay] Champion skin changes to normal skin in next game

Hi. I've noticed that since the new map was on, every time you pick a skin to play, in the next game, if you don't pick the same skin, you will play with the normal one automaticaly. That's realy anoying that we have to go and choose all games the skin we want to play with. Before the new map this wasn't that way. Plz fix. Good day.
