I'm trying to download the content of an entire directory from an S3 bucket. The directory contains two subdirectories, which themselves contain a bunch of files. It essentially looks something like this:

+ some-bucket-name
  |_ test/
      |_ foo/
      |_ bar/

The first time that I call downloadDir() with the deleteRemoved flag set to true, both subdirectories (foo and bar in this example) download to a local directory as expected:

target-dir/
|_ foo/
|_ bar/

However, on each subsequent downloadDir() call, something weird happens: the local target-dir ends up with only one directory left. Sometimes, it's foo, and sometimes, it's bar.

The code for the download is pretty straightforward:

var downloader = client.downloadDir({
  localDir: "target-dir",
  s3Params: {
    Bucket: "some-bucket-name",
    Prefix: "test/"
  },
  deleteRemoved: true
});

I haven't been able to dig into this project's code yet, but is there something that might immediately come to mind?
