I've got to say I'm very impressed with the progress you've made with this builder. It is much improved over it's original incarnation and I like that you can save lists and track wins and losses.
One question, I try to click the log in button but nothing happens. Facebook is blocked at my work though, could that be the problem?
Yes. Without Facebook there's no logging in. Sorry.
Edit: I also notice that when choosing Steath Device the ships agilty changes to reflect both the base and the increased agility from the mod. Would it be possible for a similar thing to happen when you take Vet Instincts to increase your pilot skill?
Why would you do that? The card's addition to Pilot Skill isn't optional. Once you buy that upgrade, the Pilot Skill is fixed at the new level.
