The only mod installed is InfinityLib v2.1.2 on forge version 40.1.51. While this doesn't seem to break anything, worlds load fine, I assume this isn't intentional.

Specifically it seems to be duplicating all "ResourceKey[minecraft:worldgen/noise /" keys.

I am failing to reproduce this...

Interesting, I am not interacting with those at all, but I'll have a look

I've tried using different launchers, I've tried changing forge versions, I've tried changing java versions, whole new instances, in every situation I get duplicate keys. I have even tried downgrading Infinity lib to 2.1.0 and it happens with that too. I updated to 2.1.3 and it still happens.

My java version is: OpenJDK Runtime Environment Temurin-17.0.3+7 (build 17.0.3+7)
Game version is 1.18.2
Forge is 40.1.51
LWJGL 3.2.2

Yes, I was testing in my agricraft dev environment, where it doesn't happen, in the InfinityLib environment, Sith agricraft I have now observed this as well.
Which is interesting, but at least, now I can pin it down and fix it.
