Hi,
I just noticed a sort of funny issue. I use a "folder.jpg" picture stored in each album folder as cover artwork for all my albums.
Since recently the file gets linked numerous and dozens of times in all files I just checked. I must assume all of my library is affected.
That screenshot is just an example. Albums I added recently have their folder.jpg linked "only" four to ten times. Other albums go up to more than 40 instances of the same artwork file!
I'm on build 2823 at the moment. Unfortunately I can't tell if the issue just started with this build or if it was present before as well. I didn't pay attention earlier.
As of now I have no Idea what causes this phenomenon and how to reproduce it.
I deleted all artwork instances except for one on some albums and tried a few manipulations with some tracks (editing Tags and artwork and auto-organizing them) but I couldn't make the additional artwork links appear again.
But I still wanted to bring this to your attention. Maybe you can make something of that regardless.
