[GS] Help with editing yields for base game improvements in Gathering Storm

[Abdou27]

I'm trying to directly modify the game files (not really making a mod because that seems like too much work tbh) to edit the yields of the Kurgan (Sythia's UI), but I can't for the life of me figure out where to make these edits, I can edit the yields of the terrace farm in Expansion2_Improvements_Major.xml (found in DLC/Expansion2/Data) and that would work, but the data relevant to the Kurgan isn't there. And editing the base improvements.xml (Found in Base\Assets\Gameplay\Data) doesn't do anything.
I'd appreciate any help...

The only place it is defined is in the base Improvements.xml file. The expansions don't alter this base definition.

Then why won't the changes I make in that file affect the game (playing Gathering Storm) ?
