Selecting one rune page - another one is applied instead
This happened to me on several games. I'm choosing a champion and a rune page - specifically designed for this champion, but when the loading screen starts I see that another runes are applied.
The interesting part is that I'm choosing to play Lulu... selecting a rune page thet I've titled "Lulu" and instead it applies a rune page called 'Morgana'. And it is applying this page specifically every time the bug happens. While I'm in the champion select screen - everything is fine - the correct page stays selected. But when the loading screen starts and you can see the runes of the other players as well - my runes are different.
I haven't found a way to prevent that bug. It doesn't happen every time though. I don't know what triggers it.
In addition - when I start a new game and return in the champion select screen - both of the rune pages are selected
