No phone FC?
For me it had the exact same phone FC problem as the Pac Man rom after the first reboot. The "fix permissions" fix did not work for me (nor did it work for me on Pac Man), but the the kill-sync, wipe contacts, wipe contacts storage, wipe phone, reboot to recovery, wipe cache/dalvik fix did work (but it has to be repeated whenever you reboot).
Data seems steadier for me on this AOKP build than it was on the current Pac Man build. [Edit: still getting some of what are either data drops or what the phone thinks are data drops]
