Bug Description

Entering Middle-earth causes a disconnect crash of some sort.

Reproduction Steps

Install both mods, enter Middle-earth, get disconnected from the world.

(The mod is ARR, but its source is on GitHub. Mod is https://modrinth.com/mod/middle-earth.)

Log File

No crash file is made. All I can provide is a debug disconnect file, the latest.log file also only contains a single error related to this as well.

Latest.log file error: https://pastebin.com/wmQqUWRY

I'd recommend joining their Discord and chatting with them about this if this confuses you.

This is a palette ID issue, which usually indicates mismatched mods/configs between the client and server. You can try ModernFix 5.20.2, which tries to avoid crashing in some of these situations, but it's generally not an issue I can fix on my end.
