Hey, my brother and I were trying to goof around with some nostalgic wc2. I set the unit properties and uncheck the use default in the map editor.
Then when creating the game on bne the unit properties don't stick (is it because we are playing in game type melee?) But it will work in custom scenario one player off of bne.
EDIT: Thanks CLAW, turns out we had to set up player properties as computers and use the game type 'use map default' to get what we wanted.
