`DiffusionRepositoryEditMainController.php` explicitly access the repository directory on the current host, rather than using Conduit. This causes it to reporting incorrectly that the storage directory has been deleted.
The offending code looks like:
```
if ($repository->usesLocalWorkingCopy()) {
$local_parent = dirname($repository->getLocalPath());
if (Filesystem::pathExists($local_parent)) {
```
