Crash with sodium 0.8.12 alpha 4 on neoforge 1.21.1 when entering a world

[Starcage1]

Hi!

I've encountered a crash when entering a world. The game reaches the main menu normally, but crashes immediately when loading into a singleplayer world.

Environment
Minecraft: 1.21.1
Loader: NeoForge 21.1.233
Supplementaries: 1.21.1-3.6.7

crash-2026-06-13_14.47.51-client.txt

Sodium: 0.8.12-alpha.4+mc1.21.1
Description

The game launches successfully and reaches the main menu. The crash only occurs during world loading, when Sodium initializes the world renderer.

The crash report points to a failed mixin injection from Supplementaries:

CompatSodiumFluidRendererMixin from mod supplementaries failed injection check
Scanned 0 target(s)

and occurs while Sodium is constructing:

net.caffeinemc.mods.sodium.neoforge.render.FluidRendererImpl
Relevant Exception
org.spongepowered.asm.mixin.injection.throwables.InjectionError:
Critical injection failure:
CompatSodiumFluidRendererMixin
from mod supplementaries
failed injection check,
(0/1) succeeded.
Scanned 0 target(s).
Additional Notes

This appears to be related to Sodium compatibility code rather than world content itself, as the crash happens before the world finishes loading.

Full crash report attached.

Thanks for taking a look!
