The League client records many statistics about your battles. Some of these include who you played against, how long the game was, and other things like that. Often when I have a game end my client crashes, or I end up stuck at a 'waiting for stats' screen with an option to click a button and skip the wait.
In both of these circumstance my client does not display most of my information about the last game. Some of this information is often important to me. IE: The name of the Kat who afk'ed so I can report her. Or the number of assists my support had so I can post our game stats on facebook. Those are but two examples, I could write a thesis on how much of this lost information can be usefull.
Is there anyway I can retreive information that has either been hidden (too long ago in my recent matches list) or that was never displayed at all due to bugs or such.
