Using Easy Mode - think twice before using

Anyone using the Easy Mode option to create a theme might want to think twice.

Have tried using this a few times now and seem to always find at some point it will not save (build) the theme and get an error message 'There was a technical problem saving this theme'

No matter what I do it will not save and so all the work done changing colors (buttons, header, even own custom.css is lost as cannot save and so have to start all over again which for me is a complete waste of time)

Am using RC7a and this still happens
