I just started playing this last week, and although the learning curve is pretty steep, I seem to be doing okay. I have a vulcan science officer, and currently I have a Constitution class cruiser, about to make Commander in 2 more missions.
I have scratched my head quite a bit trying to figure this out, and I can't for the life in me, get this to work. In the "U" menu, when I look up the ship, and go into positions, I see I can appoint 4 bridge officers, 2 for engineering, 1 for science, and 1 for Tactical. I was able to appoint an officer for every position, except for the science position. I have been upgrading their skills as I go, even promoted him trying to get him into the position, and so far, I haven't been able to get that guy into that position.
To make matters worse, I just did the planet killer mission, where I borrow a Klingon ship, and upon successfully completing that mission, now I am unable to fill any of those 4 positions on my ship. No matter what I do, I select their names in the drop down list, and selecting them does not put them in the position.
I know the learning curve is pretty steep for me, but any idea what the heck is wrong?
