[XML] Code to make a playerperk grant a free building in every city isn't working, and I'm not sure why

The building is showing up in the civilopedia and is unbuildable otherwise, as intended, but the code to grant it isn't working and the Database log doesn't show an error.

I'm using the modular building quests mod resource, and the idea is for a quest perk to give a the building in all cities.

This is the relevant code. Is it possible that trying to add yields to the reef feature is causing the problem?

Code:

<PlayerPerks>
        <Row>
            <Type>PLAYERPERK_UTOPIA_PROJECT_ALL</Type>
            <Help>TXT_KEY_PLAYERPERK_UTOPIA_PROJECT_FOOD</Help>
            <Freebuilding>BUILDING_UTOPIA_FOREST</Freebuilding>
        </Row>
        <Row>
            <Type>PLAYERPERK_UTOPIA_PROJECT_TILE</Type>
            <Help>TXT_KEY_PLAYERPERK_UTOPIA_PROJECT_CULTURE</Help>
        </Row>
    </PlayerPerks>

Code:

<BuildingClasses>
        <Row>
            <Type>BUILDINGCLASS_UTOPIA_FOREST</Type>
            <DefaultBuilding>BUILDING_UTOPIA_FOREST</DefaultBuilding>
            <Description>TXT_KEY_BUILDING_UTOPIA_FOREST</Description>
        </Row>
    </BuildingClasses>
 
    <Buildings>
        <Row>
            <Type>BUILDING_UTOPIA_FOREST</Type>
            <BuildingClass>BUILDINGCLASS_UTOPIA_FOREST</BuildingClass>
            <Cost>-1</Cost>
            <ConquestProbability>0</ConquestProbability>
            <PrereqTech>TECH_HABITATION</PrereqTech>
            <Description>TXT_KEY_BUILDING_UTOPIA_FOREST</Description>
            <Civilopedia>TXT_KEY_BUILDING_UTOPIA_PROJECT_PEDIA</Civilopedia>
            <IconAtlas>BW_ATLAS_1</IconAtlas>
            <PortraitIndex>62</PortraitIndex>
        </Row>
    </Buildings>

 

Freebuilding needs, contrary to what it states, a BuildingClass, not a Building-type.
So you need to do:

Code:

       <Row>
            <Type>PLAYERPERK_UTOPIA_PROJECT_ALL</Type>
            <Help>TXT_KEY_PLAYERPERK_UTOPIA_PROJECT_FOOD</Help>
            <Freebuilding>BUILDINGCLASS_UTOPIA_FOREST</Freebuilding>
        </Row>

 

Thanks again.
