Easydiscuss 4.0.5 compile stylesheet seems broken

Hi

We have activated timeless theme - did a test modification to default.less in the patch folder for the theme, but our modifications is not picked up. Tried clicking purge cache and recompile CSS, but again nothing. Looking through FTP, style.min.css and style.css are not recompiled in the timeless theme folder - same timestamp for last modified.

I've also tried clearing the general joomla cache - nothing has helped. Is the function broken, or how do I get easy discuss to recompile the css?

Thanks
