[Client] Does this happen to anyone else? Rune Page Bug

Hopefully this goes to the right authorities because I've never reported a bug before. I tried to play a game of ranked today and I couldn't edit my runes because the rune page edit button didn't show up. I had played a game just before, but there weren't any noticeable problems except for the game summary screen taking forever to load (it always happens so I didn't think much of it).

My beautiful team told me that I had to get gud. Another said that the idea is to code my own rune page button. I was surprised, because I didn't know League of Legends became so educational, but I'll definitely be taking up a free tutorial on learning how to code tonight.

Jokes aside, has this happened to anybody else? If so, how did you fix it?
