[CLIENT]Bug that breaks your entire set of mastery pages

Very easy to replicate. Simply name 2 pages the same exact characters with the only difference being the capitalization. Examples would include "derp" and "derP", "Leona" and "leona", you get the drift. If you do have any 2 different pages like this, when you try to save or switch pages, you get a message back with "Unexpected Platform Error." This will happen any time you try to interact with your masteries until you change one of the two pages to a different name. A very detrimental bug that caused me to go in with stupid masteries for 2 ranked games. Please spread the word and get this fixed it shouldn't be a hard fix.
