Hi all, This has happened to me in both of my last two games. I build a standard radar tower and see some enemy blips. I then build a big cannon to hit the blips. The cannon does not fire. I select the cannon and right click on an enemy blip. The cannon does not fire. I see that it is on hold fire so I switch it to fire at will. The cannon does not fire. I right click the enemy blip again. The cannon does not fire. No matter what I do the cannon will not fire. Even if I approach the enemy building/unit so that it is in sight the cannon does not fire. Even when enemy units approach it and destroy it does not fire. Big bug. Thanks, Rebuilt
