Internal Ship Turrets Not Attacking Boarder

[Zeus]

I forgot to save the replay of this, and I don't recall which game it was. I will try to see if I can find it in my recent games. But I was playing a game where my BC was boarded. The boarder was standing right next to the cannons, almost touching them, and they were not shooting him at all. It didn't look like he had the cloaking suit on, but even if he did, the cannons still should have been attacking him.

[Siretu]

There are two items. The cloaking and the frequency nullifier. The nullifier doesn't cloak but renders the wearer immune to turrets.

[Zeus]

Isn't nullifier a ship item though?

[Siretu]

It has dual purposes.

[Zeus]

Ah, I thought it only worked on the ship. He probably had that on then.
