First off, I'm having loads of fun experimenting with the beta. Keep up the good work.
In my current game playing as the Altarians, I designed my first military vessel on a tiny hull with just a lone laser I. Here are her details.

As you can hopefully see, she has a laser and an attack value of 0. I tried to attack a ship in orbit, but other than losing a movement point, nothing happened.
Has anyone else had this happen?
