When in cache mode, folders/assets data are fetched from a cache database instead of folders/assets from file system. So it might getting out of sync when the folders/assets changed.
There’re functionalities built in UAsset Browser to help resolving the outdated data issue without re-created the cache database from scratch.
Rescan
To make sure folders data up to date, you can right click a folder to Rescan current selected folder recursively.
Revalidate
The uasset dependency data is also cached once it’s validated. If you suspect the dependency data is out of date, you can right click the asset in the Asset Viewer, select Revalidate to validate the asset dependency data agian.
Reparse
Just like Revalidate will re-gather the dependency data for selected asset, ReParse will re-parse the selected asset to make the asset meta data up to date with selected asset file on disk.
