Class MY_Controller not found

[eluser]Mareshal[/eluser]
The error is on this line

Code:

class Dashboard extends MY_Controller
{

MY_Controller has .php for sure, just checked

Yes, files are in same application, but I have this pattern:
/
dev
system
index.php

My application is on the same level with system folder, everything else works.

I tried with __construct already, but same code in 1.7.2 works, so there's a problem with 2.0. Just submitted an issue on BitBucket for this
