Fiddle Standing animation Bug

Well I was playing with my beloved fiddlesticks, who had a surprise party skin. Every animation is brilliant except for one:

When I stand still and do nothing or press "s" for stop command, he is standing animated for 2 second and then the animation stops. It just simply doesn't move as if fiddle got frozen from Seju's ult. I know it's a little bug but sometimes it annoys me. Please fix my dear riot ;~; Sincerely Alliesa
