    Hey y'all!
    So I tried to join my server, but this error occurred:


    Internal Exception: com.google.common.util.concurrent.UncheckedExecutionException: java.lang.IllegalStateException: Recipe minecraft:shield (net.minecraft.item.crafting.ShapedRecipes@553d828a) produces unregistered item minecraft:shield (net.minecraft.item.ItemShield@3f6a9ba0)

    (I have all the mods that are in RLCraft installed, except Ice and Fire and Spartan and Fire are updated to the newest version, and I also have Villager Names and Collective)

    Does anyone know how to fix this? I'm using Forge 1.12.2 (14.23.5.2860)

    THANKS!

    Share your client log

    1. open your minecraft installation path

    (enter %appdata%/.minecraft in the file explorer )

    2. open the logs folder

    3. open the "latest" or "latest.log" file with a text editor

    4. copy and paste the content of the file to https://mclo.gs/

    5. send the link here

    I can't see any connection attempt to the server
