Hold up a sec Goran,
We weren't saying that the romance mod broke anything.
The problem is if you use KSE to hack your save game and actually set yourself to be both genders - which while similar, is NOT what the romance mod does - breaks the game.
Well, it doesn't "break" it, but it causes a problem in some places.. the first of which being between the Endar Spire and Taris.
It will also happen if you use the editor to make your ORIGINAL class anything but the 3 you can choose at character creation.
I know the problem is in a check in a script someplace.. the trouble is figuring out a way around it, since most of them aren't available as source - just compiled versions. =/
