Uncrafting table is not usable

[MrCitizen776]

MC Neoforge 1.21
I had to remove Octolib in order to run the mod but interacting with the table does nothing, and for some reason it takes a while to appear in the hotbar/inventory.

Can confirm latest update is broken on Minecraft 1.21.1 with Fabric Loader 0.16.10. Reverting back to 1.4.2 does work as mentioned by h4x0reL on issue #85. You could try doing that for now to get around the issue until it's resolved by the mod author.
