In LR5, when a photo using Process 2003 is selected, the Post-Crop Vignette Style is instantly changed to "Paint Overlay." It's not possible to undo past this step using Ctrl-Z or Edit > Undo. If more than one step past this Vignette Style change is selected under History, those steps end up being deleted with no option to undo the deletion. For Process 2003, the "Highlight Priority" and "Color Priority" options are no longer available for Post-Crop Vignette Style.
