Just started a new custom modpack, modlist here: https://pastebin.com/x39SCh8m
Forge: 4.1.0
IE: 1.18.2-8.0.1-147

When putting coal in the coke oven I get an "Empty Tag: forge:coal_coke" item instead of the actual item.

In the Crude Blast Furnace it won't accept the empty tag item as an input and it I use regular charcoal I get the item "Empty Tag: forge:ingots/steel" instead of a Steel Ingot.

Seems like I'm unable to proceed in the mod because of this and not sure where to start debugging this.

Try updating Cooking For Blockheads and Balm.

Thanks that sorted it! Sorry for the bother about an issue which technically wasn't from this mod.
