Have you tried turning your Shinobi off and on again?

[BasiliskXVIII]

I was playing my Storm/Nin earlier and noticed to myself it had been a long time since I'd noticed a crit. Looking back through my combat logs I found there wasn't a single instance of " You hit ~ with your Shinobi Skills for # points of Lethal damage (CRITICAL).", Shinobi was on, so I turned on chat logging, and tested. Got through about 4 missions and never once saw a crit. Now I'm thinking Ninjitsu is broken, so I hit up the beta server and make a character there, level it to 30, same as live, and test. Works fine. 

 

Come back to live and it's still not going. The power is showing as active and the little glowing pulse is orbiting the icon, but failing any other ideas, I go back to tech support. Turn it off, then on again. Immediately after doing that and my crits come back. Is this just a weird bug? Known issue? Has anyone else noticed this?
