Editing startpos files and crusader unit files

Ok, editing the campaign startpos files is easy, even if you want to play an 'exotic' faction like the Swiss.

But I get a problem when I want to remove the 'Swiss unit Bug'. The tech tree shows that you should only be able to build Swiss units (SwissHalbardiers, SwissPikemen, SwissArmouredPikemen) in Switzerland. Currently, if you reach the tech level, every faction can build at least the SwissPikemen and SwissArmouredPikemen in every Province. I tried to edit this Bug out in the Crusaderunit file (NO_FACTION SWITZERLAND at the appobriate place), but there seems to be a problem when you try to designate more than as original to one province. So after this editing, when starting MTW I get the 'New Unit SwissArmouredPikemen line....' error message and the game does not start.

Word is it will be fixed in the patch.
