Minecraft Version

1.20.1

What happened?

I'm using a self modified All The Forge 10 modpack by AMPZNetwork, which has polymorph-forge-0.49.21.20.1.jar on it.

On multiplayer, I've run into a recipe conflict for the first time between Easy Emerald's Iron Excavator and Solarcraft's Solar Wand. (Solarcraft is a mod I added to the modpack myself)

Weird thing is, there's no item in the crafting slot. I still see the button to switch between the two, but clicking on either, no item appears in the crafting slot to take out the finished product.

I did a quick test in a singleplayer world and it's working there.

I had a suspicion it might be related to having the mod Not Enough Recipe Book (NERB) installed, so I uninstalled that from the server, and the client as well, but that didn't fix the issue. I tried running /polymorph conflicts but that just gave me this in the log:

[07Mar2024 18:33:50.746] [ForkJoinPool.commonPool-worker-9/INFO] [net.minecraft.server.MinecraftServer/]: [AngelSkyheart: Searching for recipe conflicts...]
[07Mar2024 18:33:50.747] [ForkJoinPool.commonPool-worker-9/ERROR] [net.minecraftforge.eventbus.EventSubclassTransformer/EVENTBUS]: Could not find parent com/illusivesoulworks/polymorph/server/PolymorphCommands$RecipeWrapper for class com/illusivesoulworks/polymorph/server/PolymorphCommands$CraftingRecipeWrapper in classloader jdk.internal.loader.ClassLoaders$AppClassLoader@2f92e0f4 on thread Thread[#122,ForkJoinPool.commonPool-worker-9,8,SERVER]
[07Mar2024 18:33:50.747] [ForkJoinPool.commonPool-worker-9/ERROR] [net.minecraftforge.eventbus.EventSubclassTransformer/EVENTBUS]: An error occurred building event handler

So I'm kind of at a loss at this point for what to do. Can you help?

EDIT 09 Mar 2024: Ok, I just found out that the Polymorph actually IS working on the server. I can swap between the recipes of the white wool slab from Absent By Design and white sleeping bag from Comforts. So it's specifically only the recipe conflict between Easy Emerald's Iron Excavator and Solar Craft's solar wand that it's glitching on.

How do you trigger this bug?

Interestingly, this seems like a SolarCraft issue rather than a Polymorph one. Loading up just SolarCraft by itself, I can't actually craft the Solar Wand. However, I can craft Easy Emerald Tool's Iron Excavator when loading that by itself. I'm not sure why that's the case, but it's worth reporting to the SolarCraft developer instead.
