*looks through it*
I'll tell you once I find it :P
I haven't found it after looking through all of the code....I don't believe you've redefined Scene_Menu anywhere, unless I'm missing it.
One thing though, your "draw_actor_position" method is not so likely to work properly since I don't change the actual position variable. That variable is related to a class and can't be permanently changed. Instead, I change the "odds" variable, so you'd need to use that in the method instead.
