World Space material Stretching when object is rotated.

I've pieced together a world space shader including a few extra textures like Normal/Bump, Specular, Emissions and a rotation variable for the top facing sides of our cubes. I'm running into an issue where when I rotate the mesh 90 and 270 degrees the faces on the x and z axis stretch the texture as if it is holding normals for those faces and not updating to the new axis for the world space. when I rotate to 180 it corrects the texture again, however I need it to work correctly on 90 and 270 as well. Any help would be appreciative, I'm sure I'm missing something I just can't see it as I've been staring at it too long.
