Overworld Biomes Generation Bug (Microbiomes)

This suggestion calls for a fix regarding a bug in the generation of many Overworld biomes both old and new, as a great number of players (myself included) have noticed an error involving in the biomes, the microbiomes. These are biomes that are incredibly small smaller than you can imagine containing only a few trees, or sometimes no trees or other characteristic biome features at all. This bug is most prevalent in new biomes (such as the Pale Garden, Cherry Grove, or the new Dappled Forest) as well as the Mushroom Fields biome. That is why I am asking for a permanent fix for this microbiomes generation bug, the affected biomes should be made fixed and significantly larger and more substantial, allowing players to enjoy discovering biomes without the issue of stumbling upon these tiny, incomplete versions.
