Gets stuck in infinite fail loop if file used to exist but no longer does.

Fail uploading file server/data/settings.json: { [Error: ENOENT, open 'server/data/settings.json'] errno: 34, code: 'ENOENT', path: 'server/data/settings.json' }

In my opinion, this should actually be setup regardless of the error. I'm noticing that if it fails to upload a file, often times it will get stuck in an infinite loop (this doesn't happen when failing to delete a file). This is a pretty serious bug which will prevent you from practically deploying larger numbers of files, which is supposed one of the more useful aspects of this application.
