Heavy stuttering when this is extended , even if the number of weapon group is small .
Another thing is ships do a weird wobbling motion when turning (only on maunal turning and waypoint turning)
sometimes ships in a division will simply suddenly accelerate and collide with other ship without trying avoid .
AI are too good at dodging Torpedo , they can simply sense the torpedo and turn instantly , even though they shouldn't be able to detect it . Not until the torps are close enough . Example : launch torps at 10 KM , torp electric , 553mm, the moment the torps were launched , enemy warship immediately do a 90 degree turn. Making torpedo work mostly require a ship that wont get one-shot to launch at point blank range , Which is why some of my battleships have a lot of torps . (This torpedo problem are not really game breaking , but "enemy warship immediately do a 90 degree turn" are really weird. )
