The Partisans event in Civ4 is bugged. 3.19 BTS It is not supposed to occur for size 1 cities but it does anyway. In CvEventManager.py, I found the cause. The line "if city.getPopulation > 1" is missing brackets, it should be "if city.getPopulation() > 1". It almost always spawns 4~5 units because it uses the city's Tile Culture Level to calculate the number of partisan units. The Tile Culture Level of the plot a city is on grows extremely fast/is extremely high due to game mechanics. I believe it was meant to use the City Culture level instead. In CvRandomEventInterface.py, this defines the number of units created. def getNumPartisanUnits(plot, iPlayer): for i in range(gc.getNumCultureLevelInfos()): iI = gc.getNumCultureLevelInfos() - i - 1 if plot.getCulture(iPlayer) >= gc.getGame().getCultureThreshold(iI): return iI return 0 How do I change it so that it uses the city's Culture Level instead of plot Culture Level?
