I did change the IDs, though. I have them working in SSP perfectly fine, and I copied over the files from there, which, from what I've seen, solves most ID problems. Not with Jammy, though, I guess. I don't know what else I can do to change the IDs, I really want to use this mod because it's an amazing mod and adds a lot to MC, but I might have to go without unless anyone has any other ideas..?
