Cloner create_empty_blog deprecated in WP 4.5


I'm trying to use your Cloner plugin to clone a site in a MultiSite install on my local dev environment but I'm getting the notice "create_empty_blog is deprecated since version 4.4 with no alternative available".

We're running our current site with the following:
WordPress 4.5.3
Cloner 1.7.2

Is there anything can we do to resolve this as quickly as possible as we need to launch the new site early next week.
