I have a similar problem with broken links not being removed from library.
For some reason, almost my entire library has 2, 3, or 4 entries for every song. However, only ONE of them actually has a link to the actual network server with the real song. The rest of the links are broken. Furthermore, this problem appears to be growing. i.e. more broken or non-existing links are being added over time.
I have re-configured auto-import and unchecked Everything except Fix Broken Links Yes. Since all my music is on network drives, that apprers to be the correct choice not the protect files on missing drives options. I run auto-import and the broken links are still there.
Nothing is resolved.
My playback keeps crashing as MC19 tries to play non-existing links.
I have tried manually deleting the bad links from the library and that works. That isn't an option for all of the library as I have a very big library.
One last item is that this is a new system with a restored library. I backed up the old library and restored to new system with all the network drives having same drive letters on new system as old. It worked very well and everything was initially fine. This problem started some time after the new system started and it is getting worse as more broken links are being added.
What's wrong here? Am I doing something wrong is auto-import not working properly.
