Smelting Factory not working on a LAN/WAN Server

[ButterOcelot]

Issue description

I am hosting a server on my laptop for me and my friends to play on. I just updated it to the newest version of Neoforge, 21.1.133. Now our Smelting Factories of any tier refuse to work. Whenever an item is placed inside it appears back in the player's inventory, rendering the block non-functional.

Steps to reproduce

1. Download Neoforge 21.1.133 and select "install server" when installing
2. Host a server and join via LAN or WAN connection
3. Place and open a Smelting Factory (can be UN-powered or powered)
4. Put item inside
