AddOfficer doesn't work properly for officers above level 5 (or I suppose 6 if you've got that skill) - I was trying to use it to do a sortof a save-transfer-lite on starting a new game with extra mods enabled, and was hoping to keep the two level 7 officers I'd found in the previous game.
Respec is similarly non-functioning; I think what's happening here is that the game's officer-level-up mechanism cuts you off at 5 regardless of what level the officer thinks they're up to.
Also, addofficer apparently auto-elites whatever random skill they started with, which is not always what you want. (Looks like this is a result of assigning "two skill points" to said skill?)
