Beta 6 .97.5 Battle viewer doesn't show my missiles firing

In a game started on .97.5, I have now twice seen battles where the viewer shows the enemy firing lasers, missiles, and guns, while my ships (armed only with missiles) are not shown firing at all.  Yet I win the battle.  In both cases it was my 4 stinger-armed medium hull ships against a Yor starport.  Battles against starbases and fleets have gone normally, it's only these two battles against starports that have had the problem.  And there's nothing carried over from a previous game, all designs were created on .97.5.
