I am not sure if anyone has noticed this about his forward movement. I had found when playing treasure hunt with EMO, he walks slightly toward the right when moving forward. Eventually if he had an area of roughly 3m, he would be able to go full circle.
The second thing that I noticed is that he tends to move toward a blank space and stare at a wall or an open area with no activity most of the time. Even when called he will respond but facing the other way.
