Maybe another user can confirm this. I rip to two categories in my library. One for mp3 files and one for DSD versions of albums. I also scan and edit my own CD artwork and maintain a folder for those graphics. As I am ripping the DSD version of a CD, I go into my artwork folder and copy the artwork I need to the clipboard. When CD rip 1 is done I paste that album artwork in. Then without switching libraries I do my mp3 rip and when that is done I then go to paste that graphic in and it is gone and does not go. Instead it's a graphic of a horizontal bar ever time. (I after the fact delete the mp3 version from my DSD library then after a day of ripping I go into my mp3 library and import all albums from my mp3 folder btw).
This used to work under MC18 but no more.....
