You can download the complete CSS files from here (Click red button on right side of page).

I don't have special config for Webpack. And I'm not sure if it's related to Webpack or not. Also I tried to remove node_modules and reinstall packages but did not worked.

Solution

I finally found the solution. The problem is with .fontello-session file. I don't know exactly what is the problem but deleting it makes everything to work again.
