[CRASH] Loading screen crashes when you faceroll keyboard

Loading screen will stop loading if you rapidly hit keys, specifically the number keys. After it has crashed and you restart the launcher, it will ask you to (get this) find your league of legends directory and attempt to patch the game.

From a programming point of view, all I can say is wtf. also, when you do select your directory, it keeps asking you until you simply hit Ok WITHOUT selecting any folders.

step 1. start loading a game step 2. faceroll number keys step 3. after you are sure it has stopped loading, restart the launcher step 4. attempt to select directory (be baffled) step 5. fiddle with it until it somehow starts for some reason patching the game..? step 6. reconnect!
