1. Editor doesn't have anything to do with saving data as this is JavaScript application.
2. If you are able to reproduce this issue in CKEditor when switching to source and back then this can be considered editor fault and is most likely caused by combination of ACF and plugins (allowed tags used in your editor).

To learn more about ACF, please see:
​http://docs.ckeditor.com/#!/guide/dev_acf
​http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter
​http://docs.ckeditor.com/#!/guide/dev_disallowed_content
​http://docs.ckeditor.com/#!/api/CKEDITOR.filter-method-addTransformations
​http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent
​http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-extraAllowedContent

You could try below to allow everything for divs in CKEditor.

var editor = CKEDITOR.replace( 'editor1', {
extraAllowedContent : 'div{*}[*](*)'
});

@mick104 I'm closing this ticket because I think it is invalid but if this is not what you are having and you can reproduce this issue without saving and with proper ACF settings, please leave a comment.
