Have you tried disabling Optimum Seams, and setting blending to
Multiband? This will give you the same blending as v11.
Pressing the Reset button in Exposure/HDR might help.
If you need PTGui to correct vignetting, be sure to develop your raw
images in a neutral way. Don't use shadow/highlight correction, don't
tonemap the images before stitching. If you do this, vignetting
correction should be disabled in PTGui.
If you would like me to investigate, please make your project file and
source images available for download.
