Fatal Error after checkout

After I complete a purchase, on the checkout page, your plugin v1.0.9 gives a fatal error. It’s trying to call a function r4m_get_order_address() that does not exist.

PHP Fatal error: Uncaught Error: Call to undefined function r4m_get_order_address() in /nas/content/live/tynerstg/wp-content/plugins/orders-to-route4me-for-woocommerce/include/synchronize.php:26\nStack trace:\n#0 /nas/content/live/tynerstg/wp-includes/class-wp-hook.php(303): r4mwoo_sync_order(1007)\n#1 /nas/content/live/tynerstg/wp-includes/class-wp-hook.php(327): WP_Hook->apply_filters('', Array)\n#2 /nas/content/live/tynerstg/wp-includes/plugin.php(470): WP_Hook->do_action(Array)\n#3 /nas/content/live/tynerstg/wp-content/plugins/woocommerce/templates/checkout/thankyou.php(80): do_action('woocommerce_tha...', 1007)\n#4 /nas/content/live/tynerstg/wp-content/plugins/woocommerce/includes/wc-core-functions.php(345): include('/nas/content/li...')\n#5 /nas/content/live/tynerstg/wp-content/plugins/woocommerce/includes/shortcodes/class-wc-shortcode-checkout.php(256): wc_get_template('checkout/thanky...', Array)\n#6 /nas/content/live/tynerstg/wp-content/plugins/woocommerce/includes/shortcodes/class-wc-shortcode-checkout.php(63): WC_Shortcode in /nas/content/live/tynerstg/wp-content/plugins/orders-to-route4me-for-woocommerce/include/synchronize.php on line 26, referer: https://tynerstg.wpengine.com/checkout/
