Arrow class is acting wierd

[Shinami]

Quite simply put, I'm calling a slightly striped down version of the Arrow_Actor class(named Arrow_Card) but the arrow will not appear no matter what I do. I have checked the x/y/z coords and they are all defined properly. I have checked the .visible method with the print syntax(if it can be called that) and it's outputting true. I press left or right and I hear the arrow's moving sound effect. On top of that, I'm using the standardized window skin. I have even tried calling Arrow_Actor and Arrow_Enemy but I receive the same results as with Arrow_Card. I am truly and utterly baffled as to why the arrow is doing everything EXCEPT appearing.
