I am level 5 Mastery with Vayne 
, hoping to get that level 6. I already have earned one S token for her, and in my most recent match I earned an S- grade and didn't receive my token. My teammates/group who I queued up with got their usual Hextech Chest but I didn't receive anything? A bug? Any help would be great.
Zombiemaster2 votesWhat gamemode did you get the S- on? Mastery tokens can only be earned when playing normal or ranked Summoner's Rift, so if you got the S- when playing an ARAM, TT, or rotating game mode, that is why you did not get the token.
ItzBellaa1 votesAh thanks, I did get it in ARAM mode. I still most likely should have gotten that chest, like my teammates did though, right?
Zombiemaster1 votesNo. You can only earn one chest per champion per season. Since you already have one token, that means that you already have gotten an S- on Vayne and obtained a chest with her.
ItzBellaa1 votesAh, thank you very much for your time! [slayer-jinx-wink]
