Mastery 6 bugs, [client}

hello, [client]

so, I played a game and got a S+ on Yasuo and this was also the game where i got mastery level 5 with him but it popped up on the screen that i got the level 5 but also that i got a level 6 token, then when i went to the loot and crafting section the token wasn't there. i am asking for where my level 6 token is?

how to recreate this issue:

1. Go into a game with a champion that you are about to get level 6 with
2. Get a S- or higher on that champion
3. When the game is over, the client will tell you that you got level 5 and a level 6 token
4. Then if you go to the loot crafting section, your mastery 6 token will not be present
