How can we reproduce this bug or crash?

Appears in Debug Log

What Minecraft version is this happening on?

Minecraft 1.21.1

What NeoForge or Fabric version is this happening on?

Neoforge 21.1.115

What Refined Storage version is this happening on?

RS2-Milestone 4.13

Relevant log output

Full modlist please. And actual debug logs, not some extract.

Sorry for delay, missed notification that you responded. Attached is the latest debug log (last night) (includes mod list). RS2 error around line 6344

debug.log

But are there crashes? Does the game run?

no crashes, game runs, just errors in the log so far.

Probably one of these optimizer mods causing the log. But closing as there is no real issue and does not happen with stock RS2.
