Won't push new versions of existing files

When I update local files and attempt to sync them to the s3 bucket they get marked 'No change' and don't get updated.

I tried forcing overwriting existing files by setting the 'overwrite' option to true with no success.

This can caused by a cached file list, you can disable caching of the file list with cacheTTL: 0
