Ryze and Taliyah Bug.
I was playing in game as the new Ryze in an AI game with a Taliyah, and during the game, I couldn't walk through mid lane at some point in the game, because she had cast a wall (Her ULT) there before and for some reason it was bugged tot he point of It making me walk around it no matte how many times I clicked straight down the lane, I kept having to go through the jungle from around where she cast it from. Also at a couple points when I tried to force myself through, or came from the other direction, or a champion attacked me (it happen 3 times) I got stuck on a wall once, I got stuck glitching out in the middle of the lane once, and another time I couldn't get away when the AI champion could just walk through. (Maybe he jumped the wall, I don't remember) I'm not really expecting an answer back, I just didn't know how to report a bug in the game otherwise.
I had posted this somewhere else and Charlie Sabre from Riot told me to post it here. So I am.
