I'm currently in the midst of wrapping up a custom race/faction, but one problem remaining that I haven't been able to figure out. I'm trying to block a research path for this custom faction, the mounted warfare line to be exact. I've edited the faction.xml and indicated to use a customized version of the techtree.xml for the faction like so...
I've commented out the associated techs, in the techtree.xml...
But no dice. I don't see why this doesn't work. Any suggestions?
