[Gameplay] Level 5 Mastery same time as S rank.

So I had just got champion level five with Kha'zix in a game and received an s- the same game. It showed me that i did get the Champion shard after the level 5 animation with the s rank dialogue afterwards, but I didn't have it in hextech crafting afterwards. This is the first time I had seen this, I'm also assuming that it could be replicated by receiving an s rank when you get champion level 5 mastery.
