Found one very little impassibility. Switching wifi on while on lockscreen doesn't work. I have to change to homescreen then it starts. Detailed: I can switch wifi on while on lockscreen change to home and it starts automatically or go to homescreen directly and start wifi there. Both works.
By the way, this happens on 20140211 too and I have upgraded from this version to 20140222 (with wipe dalvik) directly (I'm on 5GHz). Maybe this has something to do with it. I said it, this really doesn't matter and doesn't bother me.
Rom is running smooth and battery life is good. Thanks
Edit: After a few reboots issue has gone
