[CLIENT/GAMEPLAY] - Rune Pages Display Incorrectly Between Modes

After playing a game in one mode (e.g., Blood Moon) and switching to another, my rune pages will display incorrectly - they'll show my "last used" rune page (Shyvana, in my case) in the mdoe I've switched to, but in game the last runes I used in the prior mode will still be equipped (in my example, Lee Sin). Checking the runes seems to have no effect on this bug - only switching to a new page, and then re-equipping the page I want.

1. Play a non-Rift mode, with a different runeset than your last Rift game.
2. Switch to a Summoner's Rift mode (unsure if anything other than ranked will duplicate this bug).
3. Don't switch your rune page - play with the one that is default equipped from your last Rift game. This has now happened three times with different rune pages.
