Bug between lux and swain?

So idk if this bug is just between lux and swain, but when im standing in swains circle thingy with the bird, i wasnt able to auto attack at all. I would spam click his character but i would basically just stand still and do nothing. Once i walk out of the circle/it goes on cd i would be able to attack him again. This happened multiple times in the game.Fix pls.
