Offhand I am going to guess you are accidentally sending Siege fleets into the Generalist target. If the target name is "# Star General" you want to use Chameleons as it is the Generalist target and a Siege fleet will not be capable of completing it.
no its not that it's when the battle starts it wont load till after the fleet is dead if the fleet cant auto the attack it's dead blame it on lag old computer whatever idk
