Just tested it for you WDP. The method draw_actor_level doesn't take a width argument, only the first 3.
This is the original.
def draw_actor_level(actor, x, y)
self.contents.font.color = system_color
self.contents.draw_text(x, y, 32, WLH, Vocab::level_a)
self.contents.font.color = normal_color
self.contents.draw_text(x + 32, y, 24, WLH, actor.level, 2)
end
So you just need to remove the width from the call to the original method.
