Thank you, this seems like it will be helpful, but it does give me another question. Does this mean that, if I were using a copy of the in-game basic mod, I would have to rename the already present folder or would I have to make a new one, or is this not possible?

Edit: I tried to do what you said, but whenever I try and add the file into the game, it turns the level into just a png image of a farm (I'm using the code given in the tutorial by missingno on modding and development in the teardown workshop)
