Problems with uri routing

[eluser]wiredesignz[/eluser]
CI 1.6.0 , the version I have is about 2 weeks old

Code:

// Call the requested method.
// Any URI segments present (besides the class/function) will be passed to the method for convenience
call_user_func_array(array(&$CI, $method), array_slice($URI->rsegments,
     ($RTR->fetch_directory() == '') ? 2 : 3));

if you have a $route sub-directory, rsegment[3] is passed to your function instead of rsegment[2].
