I have also changed the exported world gen settings so that temperature is spelled right and it still doesn't work.
Would you mind also trying out the datapck yourself just in case I'm doing something wrong.
I just uploaded the new one, tell me if there are other errors
Ok. I changed the spelling of the Temperature back to normal in the datapck, but the dimensions still don't show up.
Also when I load a world that has custom dimensions, they don't show up in Pre 4.
I have attatched the datapack and the export worldgen files.
Yes, that is what I mean.
