[CLIENT] Evelynn not owned even though She was purchased using IP.

I bought Evelynn with IP and as soon as i did it i went to play in Summoner's rift, Blind pick. At champion selection i was looking for Evelynn but could not find her. After the game i looked at my collection and She was not there, it says that i do not own her yet. All i did was buy her as any other champion using IP so i don't know why this happend. I hope this issue will be solved... Thank you in advance
