Interesting/time consuming problem
For some reason all of the scene saves I created in 2025 will not load properly until I locate every texture in the scene.
This takes ages, any ideas why this has happened and if there is a quick fix?
All my previous years and this years load fine.

Without more information that sounds like a library issue - have you recently added, deleted or changed any base folders / libraries since they last worked? Do you have any libraries-within-libraries?
If that doesn't help you might have to post a screenshot of your libraries with the Daz Formats expanded and a screenshot of the "Missing texture" error dialog in Daz. Also, the relevant text from the log.
Thanks, I did change the library last year. Would I need to move this year?

Again, until you can show some screenshots/logs it's difficult to know for certain.
In general, assets included in a scene that are part of linked libraries/base-paths will be saved with relative paths. This means that texture paths would begin with "/Runtime/Textures" (the case should not be important). These paths will be checked against every library/base-path that you currently have mapped under "Daz Formats" in the client in the order that they are listed. Therefore, if you had a library/base-path that included those textures last year but removed it this year then Daz Studio will not be able to find those assets as it has no-way of knowing where to look - and technically because you have also told it to NOT look there anymore.
However, if when creating the scene, your linked textures that were NOT in a known library/base-path then they will be saved as absolute paths and in that instance they will need to be in exactly the same place, down to the drive-letter (windows) or possibly mounted folder (OSX).
If, at any point you signed into your account within Daz Studio then Daz Connect can come into play and so you would now have cloud folders to deal with. In addition, libraries/base-paths are saved to the client application - thus if you are running multiple versions, e.g. Standard v4, Beta v4 and v2006/v6 then you would need to add the libraries/base-paths in the same way to each one.
Hopefully the above can help you track down where your issue is. But if you need more specific help then you'll need to supply more actual data/information.
