Breaking my own rules

Can you spot the mistake here?  This morning I paper pieced Ring 4 and Ring 5. Then I laid them out and realized - Ring 5 is going the wrong direction.  ARGGGG!!!  

I broke my own rule, which was to lay out each new ring behind the finished sections to make sure I have them all in the right order.  With this last ring today, I just followed the colors - thinking I knew what I was doing.  So now I get to pick teeny tiny little stitches out to separate those 9 sections. How aggravating!
