[CLIENT] "Masteries saved successfully" but no masteries in-game.

My last minutes masteries were "saved successfully" but didn't show up in-game.

1. Open the New Champion Select
2. Create a new mastery page
3. Fill it up with good masteries and give it a name
4. Wait until everyone picked their champion
5. When the countdown reaches 0, hit "save".
6. In the loading screen, you should notice that your keystone is missing
7. Lose promos

This bug has huge impact on the game stability and opens a flaw in the mastery system. This means that, before entering the game, our masteries are handled by the client and sent to the game server. Someone with a custom client could have 18/18/18 masteries and still play the game with them. This was possible with Wintermint but Riot Games never patched it or changed the way they are used. Having something held client-side is a really bad idea because it opens the door to unexpected bugs.

Yes I'm salty. Also, RIP Wintermint.
