LoL Client - Hextech Crafting Bug

Hi, I am having a problem with chests in the hextech crafting. I played a game as gnar and made the S grade, and got a chest along with it. When i went into the crafting, i had three keys, so one was used to open the chest. From the chest i received 150 essence, the project poro icon, and a skin that i dont remember. So, the point of this that it said that it had given me the items, but when i went to look into my crafting items, they were not there. The essence was claimed, but nothing else.
