I was comparing an attack strength against my friend with city level 22 and you on level 21. Then I wanted to attack the friend, so I clicked "GO!" on one attack screen. However, my friend haven't received any attack from me yet, so maybe I attacked you accidentally. Sorry if I did so.
Thanks, I got 10 NK coins, and I'm still trying to get more! Using my newly made spam email and random name. I'm gonna wait until the 30% discount starts again to spend my NK. Also I got all the upgrades for the Boomerang Dojo :D You wanna play co-op with me, Bloonsdtfan or SW?
