Was playing a game against terran today built a tempest outside his base and was moving in on him. The tempest kept flying in range of marines before attacking. I clicked ‘A’ then clicked on the ground behind the marines (they should attack the first thing they see) and it literally flew over the marines before attacking. So I tried to specifically target a tank and again it just kept flying closer and closer instead of attacking when in range. The only way I could get it to attack at its max range was by putting it on hold position. If at any point I clicked anything either attack move or directly on a unit, it would go into near melee range before attacking.
