Image masks on rectangular rotatable pieces

Is there a way to have a semi-transparent image mask rotate with the piece it is assigned to? This is important for me bacuase I have cards that are rectangular in shape. When I rotate them, masked, the card rotates properly but the image mask does not. It looks sloppy having a semi-transparent mask sitting ontop of a rotated card. I use the semi-transparent mask so that the player can completely read the text on their card when masked.

I tried changing the order of the rotate property, moving it before and after the mask property, but neither seemed to make a difference.

Any help is appreciated!

The FAQ is right - it was the order of my card properties. When I placed Can Rotate as the last property, after Mask, everything works OK.
