Migration problem with 4.1.1 to 4.1.2 and >

Hi,
I have a migration problem with v 4.1.1 to 4.1.2 and >.
All routing to subfolder of "Controllers" directory fall in 404 (controller or method not found)...
Any idea ?
Error appear since 4.1.2...

give some sample? did you use group?

No, I don't use group. But the code is the same with 4.1.1 and 4.1.2. But since I replace "system" folder (and many others new files for 4.1.2 and >), only controllers directly in "Controllers" folder works....
FYI my project works under IIS

PHP Code:

// change
$routes->setAutoRoute(true);

// to false
$routes->setAutoRoute(false); 


try that and see if it makes a difference.

What did you Try? What did you Get? What did you Expect?
