I am working on a new pack that is more of a "Hard-Mode" pack. I decided to make a pack for myself that is a bit more challenging, but at the same time, not so frustrating that I will want to quit after maybe a day or so. I was wondering if there was a way to where I can make it so that Botania flowers can only spawn in the Twilight Forest and that one Botania biome from Ridiculous Worlds only. I looked in the config, and there didn't seem to be a black list of where the flowers can spawn. Is there any mod or something that can help me do what I would like to do?
