I needed to add the Premium Edition of this release:
So I made the new release, told it to the use the 4 CD version as the starting point, saw that the four existing mediums were there, and added the 2 additional mediums. Everything looked great until I entered the edit and saw that there were only the two mediums actually saved:
I've poked at adding the other mediums back in one at a time, but anything I add gets classified as Medium 7, and even when I reorder them it's still Mediums 5-7. There's no way to recreate the first four. What the heck???
I stayed up late just getting all the new artists entered. Hopefully I can clean it up tomorrow...
