I dont have the exact one I was describing, however, the attachment to the email below is a perfect example of the very common combat bug, and the same principle as my forum post above. I wont detail the values here, you can see it in the game file.

Load game - look top right of Arcean AOI. You will see a line of three Terran fighters/fleet, and another just to the right of the right edge of the Arcean AOI. So far those four alone have held back the Arceans on their own for well over one game year as a result of the "...... too powerful ...... secret meeting ..... all declare war" blah blah.
Due to the armour bug, I have had to resort to cash 'upgrading' fighters to keep up hit points. Its worked, but been a real hassle and caused massive delay (hence we are now in game year five) - those four have received the Zydor Medal of Honour for bravery beyond the call of duty in the face of Galatic Bugs rofl
Ok - find the Arcean Capital top end of their AOI & slightly to the right, look a few parsecs top left of it and you'll see Terran Fleet 226. Attack the Arcean Capital with that fleet, keep attacking until all those ships in the Capitol are gone - watch the Terran casualty rate, hit values etc before each attack as reported both on the map icon, and the hit values in the combat summary screen. Then with the remnents of the Terren fleet go straight to planet Hammer II in the same turn, and again keep attacking until all is done.
(in particular, note the combat screen values after the first on the Capitol, then look at the reported damage to the fleet shown on its icon in the combat screen as the second attack on the Capitol starts. First attack on Capitol not a lot of damage shows on the icon in the combat screen, but as the second attack is starting the fleet icon shows damage from their first attack .... )
Sit back and reflect that a fleet like that against poor low grade Arcean ships should be able to rip through the whole Arcean Empire's planets one by one as the Arceans have no Military resource or planet fleet defences. Also look very very carefully at ALL the detailed hit value entries reported in combat screen in context of before and after as reported by clicking on the fleet map icon. Think laterally and try and correlate all values, not just the 'head line' values - none correlate, therefore not only is there a armour bug, there appears to be some kind of mathematical addition/subtraction bug going on - although I acknowledge both could be one in the same bug source.
Its sounds like you already have it nailed from the post above, I will assume you dont want any more of this particular Armour one unless you indicate otherwise after this post.
