Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Short description of error
Linked and library override on a cloth object deletes "Disk cache" when file is saved, leaving only the directory but no cache.
If you link and library override an object, then add cloth to it, the file cache stays.
The other issues are that the cache information isn't yet exposed for the library override system.
Exact steps for others to reproduce the error
Go to the cloth physics tab and under the cache settings turn on the Disk Cache check mark
Sim the mesh to create the cache, save the file.
Open the file and see that there are no frames on disk
You can then look at the cache folder on disk where your blender file was saved and see it is now empty.
Also the add and remove cache and rename the cache is not exposed to the override system, seeming like it was just overlooked when the cloth was added to the override system.
cloth problem example files.zip
example test files included
one file has a cube with cloth added, linked.
the second file has only a cube linked and then cloth was added after the link and library override.

One workaround is to make sure to turn on the Disk Cache setting on the cloth before linking in the file to have it keep the cache.

Changed status from 'Needs Triage' to: 'Confirmed'
Checking this with 3.2 version, I can't enable disk cache on overridden data, but I can confirm, that baking does not produce files. I am not 100% sure this was implemented aready though. From reading #82503 there is still limited support
