Mod breaks LAN server

[SystemlessDev]

General Troubleshooting

• I have checked for similar issues on the Issue-tracker.

Steps to reproduce

Tested with:

• TemporalSmith: Aetheric Arsenal Expansion 1.20.1-1.1.0-beta.1
• RealYusufIsmail Core 1.20.1-1.0.3
• Kotlinforforge 4.10.0-all
• Forge 47.2.0

Instructions:

1. Start two clients
2. Use client 1 to make a singleplayer world and open to lan
3. Join with client 2 and see user be kicked with error message

What is expected?

Lan server works

What is actually happening?

Client is kicked with the message on the second instance

Any additional comments?

No response

@SystemlessDev do you mean 1.20.1-1.1.0-beta.1 instead of 1.20.1-1.1.1-beta.1

[SystemlessDev]

I did, sorry about that. A little mistype 😅

[RealYusufIsmail]

I ran LAN on my game with the my mod and did not recieve this error. I dont think this error is from my mod. Are you running any other mods

[SystemlessDev]

No, I am not running any other mods than the ones listed in the original issue.

Here's logs from a test session with only your mods. Sadly Minecraft doesn't log this very well.
Debug log server: https://paste.essential.gg/CVFjNWT3Kf
Debug log client: https://paste.essential.gg/giAm2JH64c

Essential makes Minecraft log the exception caught. Here's a copy of that exception.
