Cloner plugin (v. 1.7.1) not compatible with Woocommerce 2.4.7?

Hello,

the Cloner plugin (v. 1.7.1) doesn't seem to be compatible with Woocommerce 2.4.7.
After cloning, the order items (and some other things) are missing. George, a previous support contact, told me to explain "that the order is copied over in the database table (order_items) when cloning a site, but it doesn't show up on your WooCommerce panel." .. though for me it looks like the new order_items table is just empty after cloning.

What can I do?

Thanks!
