Weirdest thing happened today at (what was) RHD's tower... around half the NSDs I tossed off were responded to with the message:
'Player so-and-so was not affected by your nano program.'
Same yellow text, just like trying to root/calm uber bosses and ICC guards!
Didn't confirm, but I think it only happened against people from the guild who's towers were under attack. I've never seen this before... in a tower battle, or anywhere else. Is it some new bonus for defenders?
