Describe the bug

When breaking a block that was under a snow layer the server crashes.

I deleted the original world where this happened, created a new one, and placed snow layers on a block and broke it to get the same error.

Removing ConquestReforged and breaking a snow block the game does not crash.

I'm not able to reproduce this with just Conquest Reforged (from 5 days ago)

I built a custom SF off of the latest: spongeforge-1.16.5-36.2.5-8.0.0-RC0-universal.jar.zip it has a simple change to the thread wrapper to better capture errors like this (hopefully).

Could you re-test and provide a full debug log and maybe a zip of a server with a flat world where this happens?

• spongeforge spongeforge-1.16.5-36.2.5-8.0.0-RC0-universal.jar : spongeforge (1.16.5-36.2.5-8.0.0-RC0) - 1
• mods_folder ConquestReforged-
mc1.16.5-5.0.6.jar : conquest (5.0.6) - 1

Note, I tried to reproduce this by placing Snow on a grass block and then breaking the grass block. Nothing happened aside from the expected block breaking.

Still getting the same thing.

Here's a gist of both normal log and debug, as well as the docker-compose file: Gist

Here's a zip of the world: World

Here's a zip of my whole server folder: Server

I can’t complete the server download (it keeps capping at 100kbps) is it reproducible without the world itself? A fresh world being created and just placing snow on grass and breaking it? Is this reproducible outside of this special docker setup?

I created a new server on my Windows 10 computer with the same Forge and the spongeforge jar you provided. I also updated Conquest Reforged to 5.0.7. I still get the same error.

I've tried placing the snow on different blocks and I still get the same crash.

This breaks weather I am in survival or creative, and op or nonop.

Sorry about that. Guess my upload speed just sucks.. Anyway here's some Google Drive links:
World Docker
Server Docker

EDIT:
After some testing it looks like the true error is that breaking a block with a snow layer in your hand is the issue. If i place a snow layer down, then switch to an empty hand. It works as intended. But as soon as I break any block with or without a snow layer on top of the block with a snow layer in my hand the server crashes.

Still getting this same error with Conquest Reforged 5.0.8 and RC1112 of spongeforge.
