Not sure where to report, but I'm seeing that only files that you edit are receiving value (https://github.com/css-modules/postcss-modules-values) changes. Is this the intended behaviour or possibly a bug? Took me a few minutes to realize what was going on, results popping in minutes later. Also if you have a file like colors.css, edit a value, nothing sees the change, until you edit those files.

I don't know the underlying mechanism for browserify etc so I can't comment on what would be going on, but it seems broken.
