New Champ Select Skin Bug [Crash] [PBE]

When you go to pick a skin that you do not currently own in thew new champ select (On PBE) and click the 'Done' Button underneath my client crashed. This has happened to me twice now.

Also you you cannot buy skins in champ select, did you take out this mechanic?
