Running latest version of TA as updated through impulse.

Recently was in a war with the Drath who use beam weaponry. I updated my ship designs to use shields to compensate.  We eventually agreed on a ceasefire, but a few turns later the Yor declared war on me.  Not having time to rebuild/redesign my fleets I sent them into battle against the Yor who use missile weapons.  Shields are offtype defense but should still roll as the square root correct? I am getting no shield animations when the missiles hit during the cinematic battle and the scrolling combat info doesn't even seem to register that I have shields installed on my ships.  It's almost as if the missiles were ignoring my shields completely. Can anyone offer an explanation?
