fatal error on missing products

recently seeing this error in the logs:

PHP Fatal error: Uncaught Error: Call to a member function get_id() on boolean in ti-woocommerce-wishlist/templates/ti-wishlist.php:68

line:

$post = get_post( $product->get_id() );

rather than handling the error here, the real error may be in product.helper.php l.399+
$_products = wc_get_products( $args );
the wishlist $products is updated with information from the woocommerce $_products if such information exists, however products which no longer exist are also left in the array without getting their data set.
