AI error?: mine clearing

[JFMahon3]

Hello,

Thank you for developing this game. I've enjoyed the combined arms aspect a lot! The surprises in the scenarios are great too.

I noticed something funny with the AI while playing the Guadacanal scenario as the allies (on second-level difficulty). I mined my entire perimeter around Henderson field early in the mission to slow the Japanese advance. I had expected the AI to bring forward engineers to clear the mines and attack my position. They did bring forward engineering units, but they did not clear the mines. Instead, they sat next to the mines for the entirety of the mission.

Why didn't the AI clear the mines? Is that an AI mistake? Is it because I'm playing on a lower-level difficulty?

Thank you for the your response.
