Please describe the new feature or change.
Requesting support for crafting tables made of the different woods from the mod "Oh The Biomes You'll Go." (BYG)
https://www.curseforge.com/minecraft/mc-mods/oh-the-biomes-youll-go

Please describe why you want this feature.
BYG adds crafting table variants based on the different woods found in the mod. When trying to craft an item using Polymorph and a crafting table made of the wood from BYG, the output slot is blank. You can still click the output slot to get the item you are trying to craft. However, it is invisible until you click to get the crafted item.

If you need a test environment, you can download my current modpack, Parity: https://www.curseforge.com/minecraft/modpacks/parity

Works fine for me. Am I missing something perhaps? Also, this is more like a bug than a feature request, so can you provide version numbers and reproduction steps?

I apologize for the lack of clarity. It happens when you are using any of the variant crafting tables as the main crafting table to craft something else.

So, for instance in your picture. You create that crafting table, place it down in the world, and use it functionally as a crafting table to craft another item or block.

Just in case you still need it:
Minecraft: 1.16.1
Forge: 32.0.70
BYG: 1.0.12
Polymorph: 0.10

Thank you for this mod and your incredibly fast response and fix! I'll be adding the update to my modpack tomorrow!

Well I can reproduce this now, so I'll look into it.
