The new nether biomes don't seem to be appearing even after I reset my nether and flew around. I am able to locate the new netherite stuff but I only see blue fire/fog/soul soil stuff on the surface. I tried testing my seed (-5403552360954279249) in a new world but my nether spawn didn't look the same neither were there any new nether biomes. However, I made another new world without using my old world's seed and the biomes showed up. My guess is that its just a bug but feel free to leave a comment.
