The Issue

The game crashes during weapon animation. Ticking entity
crash-2024-12-07_08.35.58-client.txt

Steps to Reproduce

I used the weapon "Antitheus" from the Weapons of miracles mod. Using a weapon on the left mouse button does not cause a crash, only the right one

I want to first say thank you! The Embeddium really helped.

I found the reason for these crashes. The whole essence of the problem was in one mod that conflicted with the deformation of blocks around the player, a mod called "Eureka! Ships! for Valkyrien Skies (Forge/Fabric)" (Without Embeddium, the game crashed, even without Eureka)
While checking with him and without him there were different situations. Without it, the flights stopped and the blocks became deformed.

Its not just an issue from antitheus, using a base EF greatsword ground shattering attack can crash your game as well. Heres a solution you can use to fix it:

Install embeddium
Delete this world and generate a new one
Try whatever you want to test again

Also just a tip: if you want to play epicfight with valkyrien skies, avoid using any mods that affects the lighting engine eg. starlight
