No error on class not found about core

Possible solution

    #Loader::loadClass
    public static function loadClass($class) {
        $class_file = str_replace('\\', '/', str_replace('_', '/', $class)).'.php';

        foreach (self::$dirs as $dir) {
            $file = $dir.'/'.$class_file;
            if (file_exists($file)) {
                require $file;
                return;
            }
        }
        trigger_error(sprintf('Class %s not found', $class), E_USER_ERROR); #handle class not found
        # throw new \ErrorException(sprintf('Class %s not found', $class), E_USER_ERROR);
    }

Flight intentionally does not throw an error when it can't find a class. This is because PHP class_exists function tries to autoload class by default and throwing an error causes issues with third party libraries. This seems like more of an issue with the router or dispatcher. I'll take a look.

Now fixed in commit 6696c0d. It should now throw an exception for invalid callbacks.
