Saving Rune page doesnt Save

Hey guys, I was playing URF and noticed this started to happen a lot recently where I would make a Rune Page change but it actually not saving. I would hit the Save button at the top of the rune page, it would grey out and when you put your mouse over it it would say "No changes need to be saved" and then you would exit out. Another Box would appear saying something like "your runes haven't saved. Do you want to save them" I would hit yes but most of the times it reverts back the changes... becomes awkward playing Tristana with Galio top runes....
