Production overrun with Duplicate ID warnings in 25.62

Thanks @mattchristensen! This clears it up. I noticed it happens to me when choosing "Export Selection as Premiere Project" - but now I know, Save a Copy is the way.

There is one assistant editor who has no overlap with me on which projects they're in.

To be clear, this issue appears and disappears without me doing anything other than restarting Premiere. It seems there is no tangible thing to fix in my production, it's just a software bug.

Never saw this prior to 25.6x

@membrillo6 Are other editors working in your production at the same time as you? If so it's possible one of them is creating the duplicate project IDs. To be clear – the contents of the project don't matter. Every project gets a unique ID written into the project data, and that is the ID Premiere Pro is checking for when in a production. A production will work best when all projects have unique IDs, and so this system is alerting you when two projects have the same ID. Duplicating projects via the file system, or Save As, or Save a Copy will all create projects with the same internal ID, and thus cause this alert. Using the "Make a Copy" command in the Production panel will enforce a new ID. If you were able to privately send me a ZIP of your production folder I could take a look but otherwise I'm not sure what else to suggest.

I'm aware of that feature. I checked which ones and they were projects I haven't touched in months that have no duplicates by name or contents. After resetting premiere a couple times the error stopped. But I expect it will randomly start again at some point (as it has now done a few times). I did try "save as" and "make a copy" and moving the old one to trash, but that didn't stop premiere from flagging them. It also randomly added new projects to the list. Initially it was like three or four projects, then it started flagging another one, and another one.

@membrillo6 When Premiere Pro detects projects with duplicate IDs in a production, it makes a text file in the root of the production folder which lists them. Can you go out to your folder structure and open that text file, and see which projects Premiere Pro thinks are duplicates? You can then either remove them or make a new project and move the contents into the new project, and get rid of the old one. That should stop the warnings.
