Minecraft Version

1.20.1

What happened?

Hello,

There was no issue with the mod yesterday and I also made no updates to nothing.
But today my Fabric server + client started to crash everytime I try to launch the game, pointing at spectrelib.

As a precision, i have not directly subscribed to spectrelib, the mod from you that I play is Vein Mining (Fabric/Forge/Quilt) -> when I delete it from server / client, game launches normally
(Spectrelib is not in my mod folder, but put itself in my .fabric\processedMods folder : i guess for veinmining to work)

Below is the error part of the server log (and I attach full logs to this ticket) :

Thanks for help !

How do you trigger this bug?

1. launch server / game with vein mining installed

2. server cannot launch / game crashes, pointing spectrelib

3. delete vein Mining from server / client

4. server / client launch properly

Loader

Fabric

Loader Version

0.14.23

API Version

Fabric API 0.89.3

Mod Version

For the precisions, I had created this issue previously today under spectrelib (with exact same content), until i tried without vein mining and the game launched fine so I don't know from which of the 2 the issue comes from :)

This is an incompatibility with SpectreLib and Fabric Loader 0.14.23. I'm working on an update, but until then downgrading Fabric Loader should serve as a workaround.

Oh K, thx ! Appreciate the mod btw 🥰
