Just completed Memory lane, rewards are romulan engie, tac or sci boff. Used to you could see what the abilities and traits of the boffs are before selecting one, I can't any longer. Makes it a little difficult to know what you're getting =p
hrms I just got one of the lvl up rewarded officers and got a preview on those... maybe im just confuddled and haven't done this in a bit. but still, odd though that you would get a preview on one and not the other.
