[CLIENT?]

Whenever you queue for any game, as far as I know I have only done aram and regulars, and you are trying to set up your masteries for the game coming up, I have been selecting a previous mastery I have made already or I have been picking one and re-creating it real quick: even if you have enough seconds left in the game queue until the game starts, if you are in the mastery and are changing it, or not maybe you are just selecting a different mastery, even if you have 1 second left, no matter HOW MUCH TIME you have left, even if it lets you save your masteries and it says, "Masteries Saved Successfully," then it will not save for the current game you are entering, even though it says saved. If you enter them in too late, it doesn't work. Either rework the time it gives you, or don't let anybody try and change masteries with 5 seconds left.
