Multisite Content Copier not copying gallery images

Hi there

The Multisite Content Copier works great except that it is not copying gallery images (or any images if their file sizes are too big, but I suspect that's a limitation of my server–but any advice you may have about what setting to change in my PHP.ini file would also be appreciated!)

I'm using the latest version of MCC (1.3.4) and Wordpress (4.1.2). This happens using Wordpress's default "Post" post type and custom post types. I've attached a screenshot of what the copied content's gallery shortcode looks like in the WYSIWYG editor (emptiness)

The only thought I have is that I have a function to strip shortcodes on a specific post type's single page in my functions.php which looks like this:

// remove galleries from project content
  function remove_shortcode_from_index($content) {
    if (get_post_type() == 'project') {
      $content = strip_shortcodes($content);

    return $content;
  add_filter('the_content', 'remove_shortcode_from_index');

But I doubt that's the issue, right?

If this problem can't be resolved I'm sorry to say it would be a dealbreaker. So any help is appreciated! Thank you!
