Version 3.6 Custom Menu

Hi

I made an update from a customer site to version 3.6.
Till i made this update, i’m note able to work with child sites on custom menus.
So all my 21 sites are now at the parent level.
Could you please tell me when you fix this problem.
This appear on my custom theme as on a out of the box wordpress theme.
I also tried it on a complete new installation of wordpress without any plugins.

Like i read in some forums i’m not the only one with this problem. so please let me know, when you’re able to fix this or if there is a way to downgrade to an older wordpress version.

anyway thanks a lot for your great work with wordpress!

Regards
Thomas
