[BUG] Using the Primitive Alloy smelter crashes the game/server

[ArcadeArchie]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Currently when trying to make Dark steel ingots with the Primitive Alloy smelter it crashes the game/server
and it keeps crashing when restarting/re joining

Expected Behavior

that it should smelt the ingots normally without crashing

Steps To Reproduce

1. Place a Primitive Alloy smelter
2. Open its interface
3. Put in the materials needed for Dark steel ingots
4. Put in coal as fuel

Environment

- OS: Windows 10
- Java version: Adoptium 17.0.2.8-hotspot
- Minecraft version: 1.20.1
- Version: 6.0.6-alpha

Anything else?

Used in AllTheMods 9 modpack(v0.0.44) on a server
