@P3drin_Abover yes, but I do not think this is specific to any specific world seed.
Create a world in a version before 1.18.
Find a mountains/extreme hills biome that has snow in it.
Update the world to version 1.18 or above.
All snow, which would appear at the minimum of y-92 in these biomes pre-1.18, will melt if it is below y-120. Nor will it snow below y-120, (I've done tests to get the layer y-120, but it may be off by 2 or 3 blocks)
