When I attack players I sometimes see they still have diamond mines, even though that event finished long time ago. I even took screen prints on 2 occasions but I'm not sure if I should report them. Any ideas?
If the base in question has a league medal showing then they have logged into the game and raided in the current league season. I have seen the diamond mine recently on an active players base.
Not sure it's worth reporting for the canned response.
