Aside from figuring out how to fix the obvious, I would probably suggest you make the MP reporting marks a little bigger.  I just saw a couple of those Saturday evening.  Though it didn't have an upside-down MP on the side.  :hehe: 
Make sure if the texture has both sides in it that you make one of the MP's upside down from your point of view.  Shouldn't be hard to figure out which one to flip from the texture, but if it is, pick one. Not the right one, flip it back and flip the other.  Best idea I can think of right now...
