Themebuilder used to export non compiled css

Now it's only compiled, and it's not easily plug and play with my current npm bundler.

Please bring back option to export non-compiled css

I am getting this error, but am not able to revert the changes nor does it say where exact the error is. Do I have to start all over again!?
In my opinion the whole ThemeBuilder is still in Beta.

I suggest to implement a protocol tool with which you can revert the last 10 changes made in to the theme!
