You are quite welcome.
We looked at the differences between version 1.0.7 and 1.0.9 to see what could be causing the issue. We were unable to locate any significant change in the method used to retrieve the content that would cause the issue that you described.
As you are likely aware, any shortcodes within the content are executed before it is included on another page, but the scope of what is retrieved is limited to $post->post_content or $post->post_excerpt, depending on the shortcode "content" argument.
We did replace the wpautop function that was being run on the content with "the_content" filter, but that does not seem to be the culprit.
If it is not too much trouble, could you disable all plugins except RPS Include Content 1.0.9, update the page containing the rps-include shortcode and see if the problem persists? If it works you would just need to activate plugins until you find the conflict. Let us know.
