So i was soloing a Dominator in the simulator with a Hyperion, and i tried to ram the Dominator in its exposed backside to finish it off. But it diddnt take any damage. Its shields was up, but they are only 180 degrees. I managed to replicate it later in the sim aswell. Seems to only happen when the Dominators shields are up.
How to replicate:
1: Fight with a Hyperion vs the Assault Dominator (Thats what i fought atleast, might work on other ships).
2: Get behind the Domintor.
3: Ram it when its shields are up. (Ram the ship not the shield.
4: The Dominator takes shield damage for no reason.
I can record it if someone wants me to.
