AFK System

In this game, I was gonna play a AP/Tank hybrid as Cho'gath and do a regular jungle, but I couldn't even enter the loading screen after about 2 minutes so I created another league tab, closing off the original and logged back in to reconnect. It entered loading screen within less than 30 seconds and i entered game, but as soon as I entered game, it gave that pop up notification about how it disconnected me for idoling too long, etc. (I don't recall the exact words) and that put me even further back and i got put into low priority queue. Please fix this, It's certainly not the first time it happened and I don't think it will be the last if it's not fixed. Thank you.
