**Short description of error**
I have an object with the wrong material on it name "frog". I go into the materials pane and change slot 1 to "frog skin 2". I save the .blend file.
When I open the .blend file again the material in that slot is "frog skin" once again (not the new material I just selected and saved).
I will attach the .blend files (there are two since materials and armatures are linked)
