Yep. As far as I could see, you had no control, who or when to attack. And you can even befriend the people that attacked you. But, as far as I can see, you cannot actually take revenge on an attack. Only put that skull on them.
The double attacks seem to be a bug. I have also seen double stealing and double friendship requests. The timing is off.

So it seems there is control over your attacks after all. There are buttons to the right I did not see previously. It seems you can attack your friends, your foes and a random player. The wheel only gives you a attack, but not a fixed target.
Noooow, if there were a way to know, if the target has any shields up...
And if I click the locations of my friends, sometimes there runs a girl left and right. Clicked several times, she drops goodies.
