Massive Planetary sheild not working

[DirectorTsaarx]

Atrocities: I assume you're talking about the unique tech "Massive Planetary Shielding", not the planetary shield that just prevents the planet-destroying weapons.

Unfortunately, I've only ever built one of those facilities, and ended up scrapping it later when I cleaned out that particular system and the planet was no longer in immediate danger. So I don't know how it affects combat. Can you replicate the combat in the simulator? Or even just try the combat replay (assuming you haven't continued the game so far that you can't access the replay anymore)?
