Default [Q] Omnirom Nightlies unstable

The latest omnirom nightlies have major errors on samsung galaxy note 10.1. Can someone tell me why that is the case...for instance the notifications (wifi tile, brightness tile etc) won't come down when swiping down and the whole rom feels unstable. I had to use omni-4.4.2-20140602-n801x-NIGHTLY.zip in order to get a somewhat stable rom
