might just be the polarized tetryon beam arrays. these are the ones acquired from "The New Link." Not sure if it matters Klingon or Fed side, I just realized this was a Klingon Fleet yard thread. But I was looking to see if anyone had noticed trouble with these weapons.
now that I'm thinking about it, I looked for patch notes that said they changed these or added them, but I can't find anything mentioning them at all.
