Yep! You are right, I have noticed that as well.  I certainly hope they get it sorted out it is annoying to find a material I created for a scene dissapear and I did not save the material seperate.  

On a lighter note, I liked the covered bridge you did.  I have been asked to paint so many of those scenes early in my career and now they are dissappearing fast.  We only have a few left in the Tri-state, the States do not want to maintain them anymore.  They sure are beautiful.
