Mod version (NOT Minecraft version)

1.21.5-r8

A description of the issue

So, when I tried to launch the instance with Enchancement 1.21.5-r8 installed and waited for a bit, the game just crashed. However, when I downgraded the mod to 1.21.5-r7, the game launched just fine without any issue.

As you can see here, I can launch the game just fine with Enchancement 1.21.5-r7

Odd, the Buoy magma block mixin is failing even though it's just a simple ModifyExpressionValue; I have suspicion another mod is completely overwriting the magma block step method. Could you try removing mods until it stops crashing to see which one is causing it?

I looked further and it appears to be a new incompatibility with Quad. I'm not sure what they're doing to magma blocks since their source is unavailable, but I suggest reporting to them. I'll see if I can look into more detail soon if you don't get to it before me lol

Fixed on my end, they'll fix on their end too for other mods that mixin into magma blocks eventually. Gonna make some other changes and then publish the fix.
