The YarnSpinner Unreal plugin imports per-language localisation CSVs (listed in the .yarnproject) as UDataTable assets and reimports a CSV only when both its timestamp and MD5 hash have changed; it does not generate the CSVs or flag stale translations, and handling of renamed/deleted/updated projects' localisation assets is left as TODOs.
