Well this should be in the bug report area, but I cannot post there, so this seems like the closest forum to post in. I would ask that this post be moved into that forum, but then I probably won't be able to reply in there.
Like the title says, I can only find Plasma Torpedo's for upper admiral ranking on the exchange. I've put two Mk XI plasma cannons on the exchange, but a search for them does not reveal them. I can find all the plasma weapons below that rank, but at UA, only torps.
Is this just a problem limited to me, or do others have this issue as well?
