Bump!

well, I thought I could post the (little) information i got (from the export_descr_buildings file)

Code:
			} 
            faction_capability
			{    
				upgrade_bodyguard 1
            }
            construction  6 
            cost  6400 
            settlement_min large_city
            upgrades
            {
            }
here is a part of the code that uppgrades the bodyguard, its the only thing i can find that seems related to uppgrading units.
so, does anyone know something that may help in some way?
