EA, if you use a terrain paint, it should be available to us as well

My sims are living in one of the premade lots in the new world of Innisgreen and I can't even move any of the shrubbery to give myself more space for things because there's dark dirt terrain paint under all of the shrubbery. I can't paint over it because you didn't give us any of the grass textures used in the world of Innisgreen. This is incredibly frustrating and has been for years across every world. If you use it, it should be for us to use as well. Not sure why this hasn't been understood over the years.
