Note: If this bug occurs in a modpack, please report this to the modpack author. Otherwise, delete this line and add your description here. If this is a feature request, this template does not apply to you. Just delete everything.

What happens: everytime I enter the world i have been playing with my friends it crashes. (I think because im wearing living armor and cant put it off cause it crashes immedieatly)

What you expected to happen: Minecraft not to crash

Steps to reproduce:

1. I tried to re-join
2. tried to copy the world

Affected Versions (Do not use "latest"):

• BloodMagic: 1.16.4-3.1.4-24
• Minecraft: 1.16.5
• Forge: forge-36.2
  crash-2021-10-08_22.04.00-server.txt

looks to be related to #1853, they're both crashing due to the elytra upgrade, at least according to the first line of both crashlogs.

Currently, i'd advise making a backup of your world, then trying to downgrade Blood Magic to the previous version and see if that helps. If it does, take off the living armour and stick it in a chest, then you can upgrade again - or wait, if you'd prefer.

We're looking into a more permanent fix right now.

And what can I do to fix this problem?

In my case I didn't do any upgrade (just to be sure we are talking about the same thing)

How do i Downgrade the Blood Magic Mod?

Download this version (it's the second-newest one, one version behind) and replace the version you have on all clients and servers with this one.
