I will take the other Elven shipset then.

I would rather fix the mod before starting the game, to save future hassle. However, you wouldn't need to alter the Empire files, as long as neither the Culture file (I ought to check this one, since it may not be the case. *Curses faulty memory*) nor the Advanced Trait file are altered. These two invalidate any Empire file when they are altered, and likely the min/max/threshold in the settings. (Changing the costs for the actual characteristics do not invalidate Empires however) Unless it happens when you update a game which has yet to be started on PBW.
