I have 3 fleets on a system, yet when the battle starts only 3 LCs and some escorts from those fleets show up, despite me also having 2 Cruisers on those fleets.
This is incredibly frustrating as I try to fight off superior fleets with my mediocre ships while I wait for one of them to die (and potentially lose an admiral because for some reason admiral ships always show up) so the rest of the fleet can show up.
