Describe the issue

The Monumenta server has a custom resourcepack that makes use of ETF. When playing on this server, rendering a certain player caused a null pointer exception and crashed the game.

Crash log

crash-2023-12-12_14.05.50-client.txt

Your setup: (please complete the following information):

• Minecraft version: 1.20.1
• ModLoader: Fabric
• ETF Version 5.0
• Does the issue persist with only ETF installed? Impossible to check given the circumstance.
• Have you checked the FAQ in the Readme, or Discord, to see if it is a known issue? I have checked both.

I'll look into this, version 4.6.1 should hopefully be stable for you in the meantime

related to shoulder parrot entities, fixed in 5.1 - not yet released
