How to make city-placement remove all tile improvements?

[DutchGamer]

When I build a city ingame, it keeps all the terrain inprovements on that tile intact.

I want this to change, when a city is placed I want it to remove all tile improvements present.

I am not succesfull in making the game doing this, here is what I tried so far :

I edited some txt files in the folder :
C:/program files/Activision/Call to Power 2/CtP2_Data/Default/Gamedata

In the file :
terrain.txt

Spoiler:

I changed :
EnvCity {
Score 10
Food 20
Shield 25
Gold 15
Defense 0.75
Movement 50
Freight 50
}

into :
EnvCity {
Score 10
Food 20
Shield 25
Gold 15
Defense 0.75
Movement 50
Freight 50

Excludes:Road
Excludes:Farm
Excludes:Mine
Excludes:ATM
Excludes:LandDetector
Excludes:OceanRoad
Excludes:OceanFarm
Excludes:OceanMine
Excludes:OceanATM
Excludes:OceanDetector
Excludes:Structure2
Excludes:Structure1
}

This gave an error, and caused game not to start.

Next I changed the file Units.txt

Spoiler:

I changed this :

## UNIT 13

Into this :

This too caused the game to fail at startup.

Neither the Terrain nor the Units database knows the Excludes, so you can't use them there, in the standard game you could remove the terrain improvements via slic. In in the Apolyton Edition it is possible that they are removed or have no effect, but I don't remember.
