Why can't I rename a unit? Every time I have done this in the editor, the game crashes once I try to build the sucker! To test this, rename your Jaguar Warrior and start a game with Aztecs. The game crashes immediately.
Yuo need to rename the Art\Units\Unitname directory and the Art\Units\Unitname\Unitname.ini file to Art\Units\NewUnitname directory and the Art\Units\NewUnitname\NewUnitname.ini
