Yesterday I've installed this ROM+opengapps+superSU and have no problem with it. My steps:
1. I've updated TWRP recovery to 3.0.0-0
2.Go "Wipe">"Format Data">type "yes"
"Wipe">"Advanced Wipe">select all partitions and swipe to wipe
i spoke with someone on omnirom community on g+ who says this issues is fixed on the next nightly (13/02)
have trouble with google calendar, lost storage authorization in app settings, am i the only one?
