Lock file initialized. Deployment complete!

However, no directories were made on the s3 side, and filepaths that are meant to be accessable with a "/" are replaced with "%5C"

e.g.
http://s3-region.amazonaws.com/bucketname/magento%5Clatest%5Ctemplates%5Cmagento-master.template.json

instead of
http://s3-region.amazonaws.com/bucketname/magento/latest/templates/magento-master.template.json
