[CLIENT] Extremely frequent stalled game loads

About 1 in 4 games during load. I'll get to 100% extremely fast, and bounce between 24 and 35 ping. Then nothing will happen. Either A) We all sit at 100% for 3-5 minutes, or someone sits at the same percent (say 57%) for 3-5 minutes. This makes me always wonder am I secretly disconnected behind the scenes without being told I am.

Not sure if Riot problem or what. But it is frequent and new.
