Bug of game switching runes on you.

I've had it happen 3 times today where I'll change my runes, or not change them. Then when the game loads it's in a differnt rune page. An example I played 4 games straight of blitz. On my 5th game (obviously didnt touch my rune page, mastery, anything.) I load in and have my dark harvest rune page active. Is anyone else having this error or know how to fix this?
