I was tweaking a value in a existing asset. But then, if someone else use this asset, the mods will overwrite.

So I wan't to make my change in a different asset (it add different production in the city).

I create the asset, put it in the same directory than the other. But when I test, the game don't use the asset I created.

It's like there was a file which reference all the assets and files, and say to the game what the game have to use.

I have no idea what where and how.
