Combat and movement
I have noticed that if you issue a move command to a mixed fleet that includes support only ships (no guns) and then direct the fleet to attack a target, the support ships will continue flying to the original destination.. leaving the fleet behind. Likewise if you issue queued attack commands, the non combat ships tend to fly through all queued targets instead of staying with the fleet. This obviously is not ideal. I most often find guardians and carriers wandering off...
