Skin Boost Bug
I purchased the skin boost for my Team in an 5 vs 5 Aram Match no one of them choosed a skin so I asked them and they responded that they weren´t able to use a skin. I was able ot choose the defender Vayne Skin. What also happend was a kind of temporarly game crash while the client launched the game. We were stuck in the client for about 1 minute with the note get ready the fight will soon begin. We were still able to chat with our teammates. Maybe these two bugs are somhow linked to each other.
