I can add localizations to my project, and "Export For Localization…" without issue. I then translate the strings in the exported "en.xliff" file, and import them using "Import Localizations…".After doing this, I am unable to "Export For Localization…" again. It fails with the message 'Duplicate localized resource "folder/Localizable.strings" found'.I cannot find any duplicates of this file, and think the error message might be misleading. I do have a project with multiple targets for OS X and iOS.If I remove the translations and delete the files, I can export without issue, once. Subsequent exports fails. How to troubleshoot this?
