Funny that this client bug is only getting talked about now
Ive had the bug for like 2 months where the loading screen freezes when the game starts. It surprises me that after so long it still has yet to be fixed, like wtf. Also I've seen people saying they restart their pc to get back into the game. No, that's a waste of time. Ctrl+Alt+Delete, processes, end League of legends process, then re-load the client and reconnect. Still get back around 2:45 or later but its better than resetting your pc.
