Well, I think it's a benign issue. Obviously a ship cannot attack from the sun, nor can my planet attack another. The little reticle icon is there and I can click. I get the popup and it tells me about an act of war, etc. When I choose ok, go ahead and attack, I get the message at the bottom of the screen that I am attaching, but nothing of import happens as far as I can tell, so it's easily ignorable imo.
