This bug has been a problem since runes reforged came out and riot STILL HASN'T FIXED IT
So essentially what happens is when you log in and queue up for the first time the client displays you first rune page and not the one you most recently used. EX Rune page 1 is labeled Yasuo and rune page 6 is labeled Alistar. It will have the Alistar rune page selected, but it will have the Yasuo one displayed. This MASSIVELY fucks over anyone who isn't aware of the bug. As now because of this the rune-page they THOUGHT they were going to use wasn't actually what the client said it would be. and now its your first game of the day and you're already tilted because you're A F T E R S H O C K Y A S U O.
Anyways its been 2 patches and this bug is making my life a living hell.
