There is too little context here, but it looks like the player is not active in this sector. Nevertheless, you can send us his coordinates so we can check him for third-party programs 🕵
Hmm I haven't seen that before. I know there's a glitch some people use where you can stack buildings on top of each other, I can't imagine why you would do that with your radar though.
Not really, I just recon then hit based on whether they have res if there aren't troops out. I don't hit well defended sectors, that's a quick way to get trapped and lose all your troops.
