Missing Saves from Library

Patchy_AK​  These files are all in the OneDrive folder.  Uninstalling or unlinking OneDrive doesn't delete this folder or move its contents elsewhere, so you'd need to do that manually.  First though, please make sure the game is not reading this folder anymore.  Here's how to find the folder it's using:

The other thing that stands out is that some files are missing from your oldest saved households or builds.  I don't know whether the newer ones are intact since these are the 2022 files, but do you see how you only have .bpi files for many entries?  A single saved build should also include a .trayitem and a .blueprint file; the .bpi files are not enough on their own.

Hopefully this is either an oddity of how the files are listed or is specific to these oldest files.  You'll know once you move this data to the correct Tray folder.  I would also suggest moving only the newest handful of files first, then the rest in batches.  Move everything with the same time stamp at once so you always have complete sets of files to check.
