Stuck waving after a praise

My blond-haired, blue-eyed, glasses-wearing Stephetto gets stuck in waving mode after being praised. He has been there for over five minutes and will only continue if I select him and move him around to break it.

At first I believed it a glitch, so I experimented. EVERY time he is praised, he gets stuck in the waving until I move him or close the game.

You can see a explanation of why that happens in this discussion.
