Using Fire to Clear Forest/Jungle

Yes, Max is correct.

void CvMapGenerator::addUniqueImprovements()
{
	CvPlot* pPlot;
    int iBestValue = 0;
    int iValue = 0;
    int iChance = GC.getDefineINT("IMPROVEMENT_UNIQUE_CHANCE") + GC.getWorldInfo(GC.getMapINLINE().getWorldSize()).getUniqueFeatureChance();
	CvPlot* pBestPlot = NULL;
    for (int iI = 0; iI < GC.getNumImprovementInfos(); iI++)
    {
        if (GC.getImprovementInfo((ImprovementTypes)iI).isUnique())
        {
            iBestValue = 0;
            pBestPlot = NULL;
			if (GC.getGameINLINE().getMapRandNum(100, "Unique Improvements") < iChance)
			{
                for (int iJ = 0; iJ < GC.getMapINLINE().numPlotsINLINE(); iJ++)
                {
                    pPlot = GC.getMapINLINE().plotByIndexINLINE(iJ);
                    FAssert(pPlot != NULL);
                    if (pPlot->canHaveImprovement((ImprovementTypes)iI))
                    {
                        if (pPlot->getBonusType(NO_TEAM) == NO_BONUS)
                        {
                            iValue = GC.getGameINLINE().getMapRandNum(10000, "Unique Improvements");
                            if (iValue > iBestValue)
                            {
                                iBestValue = iValue;
                                pBestPlot = pPlot;
                            }
                        }
                    }
                }
                if (pBestPlot != NULL)
                {
                    pBestPlot->setImprovementType((ImprovementTypes)iI);
                    [COLOR="Cyan"]if (GC.getImprovementInfo((ImprovementTypes)iI).getSpawnUnitType() != NO_UNIT)
                    {
                      	if (!GC.getGameINLINE().isOption(GAMEOPTION_NO_BARBARIANS))
                        {
                            GET_PLAYER(BARBARIAN_PLAYER).initUnit(((UnitTypes)GC.getImprovementInfo((ImprovementTypes)iI).getSpawnUnitType()), pBestPlot->getX(), pBestPlot->getY());[/COLOR]
                        }
                    }
                }
			}
        }
    }
}

Section in Cyan says that there will be an instant placement of any Spawn Unittype on Unique Features.

Was looking for where precisely the whole Advanced Start setup is defined so I could see why/how they block the spawning of units for it (I assume they actually go through and despawn any pre-generated units, but that would require reseting the World Unit Counter as well), and I stumbled on the Map Regeneration code section. Could be rather easy to clean that up so that regenerated maps actually work just like normally generated ones.

EDIT: still not finding Advanced Start's method. No mention of it at all in Map Generation section of the SDK. So for now I'll assume that it creates a WorldBuilder Save setup of the randomly generated map, runs city placement like as if you are using WorldBuilder, then re-saves whatever work you did and loads it like a scenario. In that case, you would skip the normal Map Generation functions I think (no random placement of anything), and thus miss this line of code. Any pre-made map should result in the same "issue".

Something to watch when clearing jungle is for a large enough jungle some will have grown back before the fire goes out... and the fire can spread back to the new forest, and bounce back and forth for hundreds of turns.

Which is hilarious when it happens to someone else

Protip: Research Bronze Working, cut firebreaks near your town, start huge continental conflagration. Profit.

whatch out for mistforms which have a chance to spawn in smoke if you have events turned on!
