I'm not sure where to post this topic. Anyway, clean up drones are pointless. If I take them into an enemy system and they clean up enemy debris, the AI just builds the turrets + mines back in the exact same spots once I move most of my military ships away from the area. Net gain: nothing. The only remedy is to destroy the command centre.
Clean up drones have a tooltip that states they remove debris permanently, preventing it from ever being rebuilt. While this is technically true (the debris is removed), there is no point when the AI will rebuild it very quickly (with engineer mkIII's, no less).
So I'm wondering, is this something that has been fixed in subsequent patches, an oversight or intentional?
