Can confirm for 1.21.8 und 25w37a - Same issue applies when changing nether and end biomes to allow for rain/snow.

How to recreate:

I created a datapack that changes every biome file in \data\minecraft\worldgen\biome to allow for snowfall and added a different one to remove the nether roof (https://modrinth.com/datapack/topless-nether/gallery ) (That one is optional though). Here is an edited copy of the datapack I created containing only the biome files:

(The demonstration datapack should run fine in 1.21.7 – 1.21.8, and while displaying as outdated, should also run fine up to at least 25w37a. The other datapack I linked is outdated, but still runs in 1.21.8, but validation fails in 25w37a.)

Create a world with at least the demonstration datapack enabled, use

/weather rain 99d

/gamerule snowAccumulationHeight 8

and maybe increase the randomtickspeed. Then observe how the snow behaves in the overworld, switch dimensions and compare.

What I observe is very inconsistant. The first time I tried to change the weather while in the nether, it worked fine, later, it would only display a change when I relog, sometimes even relogging wouldnt change anything, and snow would never actually acumilate, only spawning one layer when first generating the chunks.

The following screenshots only use the demonstration data pack in 1.21.8.

Notably, when testing in 25w37a, I noticed that the issue was now partially fixed - I now had no issues getting snow to accumilate in the end, but still had to relog to get snow to show in the nether after changing the dimension and never got snow to accumilate there.

I assume this also affects custom dimensions, but wasnt able to test how the weather behaves there.

nintendo switch minecraft - out of storage 

This is so frustrating

It has happened with me in City living.

I have more than 24gb available, also nearly 100GB on the storage card. 

Can I not move game info to storage card ?

don't want to delete more game saves, only ever play 2 games, minecraft & supermario

HELP ME!!!!!

Hi Jason, I wanted to take the time to say THANK YOU SO MUCH - you have just saved me from a nightmare as the same happened to my kids' iPads and I thought we had lost 8 months of Minecraft building.  Can't tell you how grateful I am. :o)
