I have noticed that since the 1.18 update, world generation in Java has an issue of some kind. While the seeds are consistent through versions 1.18 to 1.19, it seems that the landscape generated as part of the single biome option isn't producing what I would expect from these biomes. See the attached images. The image featuring a vast ocean is allegedly part of the desert biome. The image featuring vast fields with spawns for wolves and other sorts of animals is allegedly part of the ocean biome. In versions prior to 1.18, creating an ocean biome would often drop the player onto either a very small plot of land or directly into water. Creating a desert biome would understandably have very few bodies of water in it and was generally fairly flat. I shall note that the seeds that I used to generate these world were: "06252022" for the ocean world and "Thereoncewasashipthatputtosea" for the desert world. Both worlds were created in 1.19 but the ocean world was also created in version 1.18 and produced the same results.
