Describe the bug you're experiencing

When I use the /fillbiome command the overwritten biome doesnt visually update immediately it only displays correctly after the player enters another dimension and returns or after reloading the world

The biome is technically changed at that moment, but the F3 debug screen won't show the updated biome right away.

I know this normally wouldn't be encountered during regular gameplay I discovered the issue because of Alex's Caves' Conversion Crucible

Minecraft version 1.20.1
Forge 47.4.0
Mod list on tested:
Cupboard utilities [1.20.1-2.7]
Farsight mod [1.20.1-3.7]
The Aether [1.20.1-1.5.2-neoforge]

Reproducability

Just run the /fillbiome command on a specific area with Farsight installed
things might not render properly but the biome effects still work fine.

I tried upload video footage to make it easier to identifi but It seems I can't so I will try to explean with screenshots

So i tried to change the biome into another one

but it seems it doesn't render and change immenadly

however the mob are still spawning so I guess the function of switching to the new biome is still working as intended.

It only change render and F3 display when I reload world or enters another dimension and returns.
