[CLIENT] Match history missing

This is my first time doing this so I hope I do it right (sorry if I don't). Anyways I played three games in the last 24 hours two as Sion and one as Thresh and the Thresh game doesn't show up in my match history in the client or on the league website but it does show up on lolking, not certain what info you need but heres some anyways:

I was playing on the NA server The thresh match started around 1pm AST I play on a mac

Thanks!

EDIT

The thresh match now appears in my match history, feel free to ignore this
