[Client] Recent playstyle causing major memory leaks in Windows 8.1

Lolclient.exe slowly progresses to use more and more memory after each match. I've narrowed it down to the 'recent playstyle' feature because it goes up more with more friends online each time. The only way to fix is to fully restart the PC. It's a full memory leak since closing lolclient.exe and making sure it's fully closed and reopening it just starts it back at the same memory usage it was stacked up to. Edit 1 : This is what's causing the common complaint that pre-game lobby is lagging or locking up the client as a whole. Fix this issue, you'll fix both issues.
