I think I hv same issue, so my post can help. Cause I was considering quit playing LoL cause of this bug. When i enter the game. After loading screen with champions pictures all team mates are spawning so do I - but i cant move (recall doesn't help at all), i can move my mouse cursor but thats all. I cant: click on anything, move champion, enter item shop, click camera options button etc. I cant even click on menu buttons when i press ESC. It happens in random times (especially in first game of the day), one time its normal and then i have two games in a row with this bug. Only way i can start playing when this happens is to shoot down game client with ALT+F4 and reconnect. But this method has disadvantage too - after I reconnect i have low FPS (don't know why). Anyone could help?
