I am currently playing an insane sized map and am at turn 670. If I choose quick battle The beams, drivers and missiles shoot through the ships and all the way across the map very slowly. The battle isn't over until all projectiles are gone.
This game was started in the last 1.3whatever version and I am now on 1.41
EDIT: Only happened for 5-6 battles before I wised up and chose to view a battle. Now it's not happening anymore.
