In summoner's rift, there is a path leading to middle lane on blue teams side thats right in front of middle lanes first tier tower. It is the path coming from the blue golem buff where the mid leasher tends to usually comes through after they had leashed the blue golem. For some reason, when a purple team champion runs through this path they are always hit by the tower. No matter hard they try to avoid it, they still get hit. Whereas on the opposite side, on the purple tower, a blue champion can run past without being touched. I find this to be a minor bug, but it does sometimes gets annoying. This should be fixed.
