Lee Sin's Resonating Strike will often get stuck inside a wall instead of leaping through it to his target. I believe this is caused by the enemy being too close to the wall, like with Amumu's bandage wrap. Lee Sin's model will kind of slowly phase through the wall for a couple of seconds and then return to the starting point when it can't fit into the space.
