I know that you marked this as a solution, but I wanted to post this for others that find it. You can’t be sure of the order that plugins are loaded unless you activate them in a specific order. Updating a plugin usually causes it to deactivate and reactivate, changing the order of the array mentioned in the link you gave.

It’s better to run a function on a WP hook, for example

add_action('init', 'my_init_function');
function my_init_function() {
    if (function_exists('acf_add_options_page')) {
        $page = acf_add_options_page(array(
            'menu_title' => 'Theme Settings',
            'menu_slug' => 'theme-general-settings',
            'capability' => 'edit_posts',
            'redirect' => false
        ));
    }
}

the plugins_loaded hook would also work in this case
