I found that excessively large numbers, say 100,000, do not work and will botch the code. I'm not sure what the max is to work the highest I have is 5,000. Other than that copying and pasting that code into the Game.ini. Also adding new items such as wood or thatch will work just make sure you have the rightcode for instance wood is "PrimalitemResource" not "PrimalItemConsumable"
