[1.0] Uncaught Error: Cannot find module "../css/xxx.css"

Hi there. I have a problem with CSS importing on my production Gatsby blog.

After building and deploying (using Surge) I get the following error :

layout-component---index-ab013f8….js:6 Uncaught Error: Cannot find module "../css/reset.css"

The reset.css file is imported in the template/index.js file. Everything works in develop mode. The build command don’t fail.

The weirdest thing is that I got this error few days ago and it disappeared few days after. This error surfaced again today.

I compared with the gatsby/www source code and I didn’t see any big differences about it with my project.

If someone can help me on this I will be very grateful.
