Thanks for the reply. It's a pity that something I regard as a ludicrous oversight is actually a feature - one that the campaign difficulty appears to hinge on, according to some people. I've noticed that no matter how much I destroy the enemy harvesters, all it does is tie up their Heavy Factory - doesn't stop the AI from rebuilding turrets and spamming units, so I figured denying physical spice income has no real effect on the AI due to it having infinite resources. I realize a topic about a fix pack may not be the best place to discuss vanilla game elements, but still - what are the low power side effects? The repair rate doesn't seem to slow down after all enemy windtraps are gone, and the AI doesn't need the radar to begin with. It also does not impede them from erecting new power-hungry r-turrets, either.
