I'm trying to figure out what the best way to deal with CSS files is inside Architect.

From posts etc it seems to me that I should create a CSS file outside of Architect and then link it inside using the resources.

This 'sort off' works. So I linked a css file and then started to edit it inside of Architect. All seemed good, I could see the styles taking effect.
Save -> publish -> preview. Nothing.

After a bit of investigation it would appear that even though you edit the css file in Architect and save it and you can see the styles changing inside of Architect it never actually saves the file?? If it does it certainly doesn't save it to the same location that it loaded, nor has it created another file of the same name elsewhere.

So is this a bug or is there a correct way to deal with css files. Do I have to edit the css files outside of architect always?
