I tried to reproduce the radar bug, but I cannot anymore. All I did was selecting the radar to upgrade, then the game gave me a prompt that it’s maxed out, and I couldn’t go anywhere from the screen. I don’t know what caused it, and how it got fixed. As of aiming, I do prefer the option B. P.S. Actually, the first person that asked for the fire button was @psj3809. I wonder if he purchased the premium.
