I run 1.16.5 on my server and cannot craft furniture. I can craft furniture in a offline singleplayer world. I use just enough items, and also have the right blocks for the recipe but no item shows.

Please complete the following information:

• Minecraft Version: 1.16.5
  

• Mod Version: 1.16.5

Are you using the latest verison (7.0.0pre21)?

I just tested it and it's working.
