src/SIL.XForge.Scripture/Services/LazyScrTextCollection.cs line 122 at r1 (raw file):

            return null;
        string baseProjectPath = Path.Join(_settingsDirectory, projectId);
        if (!FileSystemService.DirectoryExists(baseProjectPath))

Wouldn't it make more sense to do:

string fullPath = Path.Join(baseProjectPath, "target");
if (!FileSystemService.DirectoryExists(fullPath)) return null;

return fullPath.
