Steve -
I've noticed this before, but I can't remember if I've told you about it, so if I have, I apologize for bringing it up again, but it's annoying.
This bug takes effect after using the battle resolver, and only affects ships with either advanced engines (Is), or with It2 (so far). The class display for such ships shows them with their modified speed, in other words, if it is a monitor with a base speed of 4, and it has an It2, then the class screen shows it with a speed of 5. However, when such a ship has been involved in a battle using the Battle Resolver screen, somehow the ship display for that ship is changed to the base speed. For the monitor that would be 4. As the ship display for that ship no longer matches the class display, the ship then shows as damaged, even though it has not taken damage.
