[GAMEPLAY] Walking up Midlane

For some reason Ive had a few games where after I log into the game, I click to begin to move to my lane, but regardless where I click, my champion begins to move straight up mid-lane. Looking at the mini-map I see the normal movement line that shows up when going long distances, but I can no change it at all. No matter where I click or what I do, my champion continues to move straight up mid. My only response so far has been to quickly disconnect to avoid dying. Upon reconnecting the issue is gone, but its normally 4+ minutes into the game which is a whole different issue. This has happened to me in 3 games, twice while playing Ashe, and once while playing Garen. I do not know what to do to recreate it, but I know that when it has happened I was using the Queen Ashe and Rugged Garen skins. I am working to get some video of the event and will post once im able.
