.daz to .duf files
It seems that all Scene files up to but not including 4.5 are saved with the file extension .daz; files saved in 4.5 have the extension .duf.
I can load my .daz Scene files in 4.5 but when I save them, new files with the same name but with the new .duf extension are created.
Some of these new .duf filescan subsequently be loaded in 4.5 without any problem but not always. Occasionally, the characters and their apparel literally "explode" Transformer-like and cannot be recovered.
