When selecting a mastery in the new champion selection screen, the name doesn't match the page that I am trying to select. Instead, it will select the mastery page above the one I click. This only happens to me sometimes, but I've noticed a lot of people mentioning that they have the wrong masteries when the game starts, much more often than before anyways. Apologies if this didn't make any sense, I can try to get a screenshot of what I mean if it occurs again.
I had this Yesterday it fixed with a relog but once in every few games it happens again
It happens to me too, a lot of times. fix it riot.
For me, it shows the "last used" mastery as the default. Except that even though it claims my mage masteries are selected, it's actually selecting my adc or support masteries instead. So every game, I have to manually select a different mastery page, and then re-select the one that was before. Otherwise I will enter the game with the wrong masteries despite the correct one being shown as selected.
