P: loses connection with files after folder is renamed

Somewhere in this thread someone asked about externalizing updates so that a new catalog can be built from the images without losing edits. My apologies for adding this to the end. 

In Catalog Settings, Metadata tab; check:

• Include Develop settings in Metadata inside JPEG, TIFF, PNG and PSD files
• Automatically write changes into XMP 

Then in the Library Module:

• select all your images 
• Metadata tab, Save Metadata to File

Then create a new catalog and import the images. 

What is lost: 

• Collections
• Edit history. If the Highlights were adjusted several times, only the final remaining adjustment will show in the Basic panel. 
• Presets 
• Anything else that is only stored in the catalog, I've not been able to find a list. Map / Book / Slideshow / etc.???

I've tested this and it worked fine on my Windows machine. Tested with V10.0. 

Additionally I keep a document for all my Preferences and Catalog Settings so that I can recreate them, if needed. It seemed that the new catalog kept the preferences but not

the Catalog Settings. 

Greg, Logan & all others: I truly appreciate the amount of time and effort you're putting into testing all these different scenarios.

(even though it shouldn't be necessary for customers to spend that time on having to convince a company that their product has a bug when multiple users are beginning to see the same problem at the same time, after an update.)

I determined last night that creating a new catalog and importing all of your images doesn't fix the problem.   It seemed to work when I had just a few images, but when I imported significantly more, the problem came back.    My only solution so far has been to make a copy of the only catalog I have that doesn't have this bug and add/remove images from there.    FYI my working catalog has about 70000 images and my new copied catalog now has about 75000 images.  

I've now determined that any new catalogs I create exhibit the same behavior, however one catalog I have works fine.  I've successfully copied that catalog and the copy works.  So now if I ever want to create a new catalog I need to make a copy of the only one that works, delete images I don't want, and add the ones that I want.  BTW, I wanted to add that the only bug I've found is that images get lost after renaming folders but moving folders/images around is perfectly fine and Lightroom tracks them just fine.  It's very specific to renaming.   

UPDATE: This one catalog that used to work fine now also has the same problem.  It worked for about 4 hours of use.  So now the problem occurs no matter which catalog I am using.

This is the information on my system and the catalog that (used to) work, while it was working.

I've not tried creating a new catalog yet. I'm not unwilling to try this, but I'm not prepared, at this time, to invest time and energy into re-importing roughly 92 thousand images into a new catalog. And I can't know, with the current available data, whether creating a new catalog would be a permanent fix for this issue. For now, I'm going to live with the bug by adjusting my workflow so that I'm renaming folders just before I'm ready to quit Lightroom. If I learn, later, that creating a new catalog and re-importing files permanently eliminates this bad behavior, then I'll seriously consider following that path.

Though we've not been able to reproduce this behavior I've opened a ticket for investigation with the team. You may be contacted by an engineer for additional information.

Thank you for your patience. 

Have you tried creating a new catalog, adding a few images, and testing to see if the problem occurs with the new catalog?    I have one older catalog that works fine, but the rest of them have the same bug.  However new catalogs seem to work ok, though I've not tested a new catalog with a LOT of images.   I personally don't want to have to create an entirely new catalog and re-import all of my images to get rid of this bug. 

My EHD is a NewerTech Guardian Maximus enclosure RAID-1, with two 3 TB Toshiba hard drives that I purchased from OWC. I've changed a few variables since discovering the problem, including upgrading from Mac OS 14.6 to 15.7, rebuilding the EHD's directory with DiskWarrior 5.2, and swapping the EHD's connection to my 2018 MacBook Pro from an external, CalDigit TS3 Plus Thunderbolt 3 dock to directly in one of the MBP's Thunderbolt ports. I also performed the recommended "Clean Lightroom Install Procedure." None of these changes have resolved the problem, which I still consider to be a bug, regardless of whether a single Adobe administrator can't reproduce the problem. It will only be further investigated by Adobe engineers, and defined as a bug that needs to be addressed, if enough end users complain to hurt the company's image, or profits. If there's any good news, it's that more people are speaking out about the same problem, and that's not a coincidence. Also, for however many people are protesting about the same issue in this forum, we can be sure that others are experiencing the problem who will not register a complaint in this forum.

How old is the catalog where this happens? I'm asking because mine is essentially "ages old" (begins in 2007) and I also went from Windows to Mac with it, and the photos and folder structure in it. Actually @Rikk had that catalog in his hands a while ago to do some repairs on it (on a different issue).

Optimization didn't break it.   I went back to my latest lightroom catalog backup of the catalog with the issue, from about 3 weeks ago... it's got the bug.
