Controllers in Two-Level Sub Directory Fail!

[eluser]Phil Sturgeon[/eluser]
I have most of my controllers in /controllers/admincp/ as this is the biggest part of my system. However with the increase in files, i tried making another subdirectory /controllers/admincp/settings/ and no joy.

Tried making /admincp/test/stuff with in index() that runs echo "poo"; but nothing there either, I just get 404 every time.

I assume this is not personal error, is this a bug others have ever run into?
