MC-138801The interactions between a biome and another biome and its variants are inconsistent
The bug
There are various inconsistencies in the generation of biomes - e.g. one biome may not interact with another the same way as its variants would. Below is a table showing the biome(s) affected, a description of how the biomes are affected, an example location (with seed and coordinates), a picture showing the issue, and notes about the way the biomes generate (if necessary).
