[Patch 1.0.0.38] Game Effect does not Exist.

[Horem]

Listed in the base games GameEffects.xml is this:-

       <Row Type="EFFECT_ADJUST_BUILDING_AMENITY" Kind="KIND_EFFECT"/>
       <Row Type="EFFECT_ADJUST_BUILDING_HOUSING" Kind="KIND_EFFECT"/>
       <Row Type="EFFECT_ADJUST_BUILDING_PRODUCTION" Kind="KIND_EFFECT"/>
       <Row Type="EFFECT_ADJUST_BUILDING_PURCHASE_COST" Kind="KIND_EFFECT"/>
       <Row Type="EFFECT_ADJUST_BUILDING_SPREAD_CHARGES" Kind="KIND_EFFECT"/>
       <Row Type="EFFECT_ADJUST_BUILDING_YIELD_CHANGE" Kind="KIND_EFFECT"/>
       <Row Type="EFFECT_ADJUST_BUILDING_YIELD_MODIFIER" Kind="KIND_EFFECT"/>

I tried to use the effect: EFFECT_ADJUST_BUILDING_AMENITY on a few new buildings. It was not working as intended. This is due to the Effect not existing, error is listed in GameEffects.log:

[393754.657] [Turn: 1] Warning: Could not build a modifier factory because the effect <EFFECT_ADJUST_BUILDING_AMENITY> doesn't exist.

My assumption is the code for this effect is either missing or broken in the source code.
