Okay, just ran into weird homming mine behavior again. Advent gravwell, 150 homming mines. They had to be cleared. Turned off the scouts auto probe. Allowed the scouts to attack mines on auto and they got slaughtered. Either the homming mines had greater range than the scouts or the scouts failed to stop outside the homming mine's range. I think this is a bug. I ended up taking the planet, mines still worked, building gardas and basically sent them on suicide missions to ram the mines. Much faster than suicide scouts.
Then without provocation, with about 50 or so mines left, they just all deactivated. My ships could run around and overtop the mines and they would not detonate. I wonder if after so many minutes of isolation the mine field goes to sleep? Could it be culture? Anyway, they are easy to kill but it was a long and tedious process. Not fun.
I suggest either the scouts have an increased radius for their mine sweeping ability, or stop prior to entering the homing mines detection radius. A big antimine cap ship abilty would be neat also, an aoe ability for the Akkan would be cool.
