right the scenario is simple, one of my colonies was attacked by a small fleet, i sent my fleet in and drove them back out and to make sure they didnt regroup i chased them to the next grav well and to the next which leads to one of their colonies, fleet legs it, i notice a group of mines (without a scout present in the fleet
) and engage the mine to get it outa the way. Next thing i know the game crashes and has a mini dump
ive tried repeating several times and everytime i engage the mines the game crashes and goes to mini dump, never with anything else, if i leave the mines well alone the games fine but soon as i engage the mines BOOM it crashes 
has anyone else had this problem?
