Describe the bug you're experiencing

The Minecraft game crashes during the server tick loop with an exception related to Mixin transformation. The error specifically occurs when the Smoothchunk mod attempts to apply a transformation to the class net.minecraft.class_3898. The transformation fails, causing a critical injection failure in the mod's code, which is related to the getSize method in the ChunkMapSlowUnload part of the mod.

Reproducability

1. Launching Minecraft with the modpack containing Smoothchunk and Sodium.
   2, Attempted to load a world or start a server.
   The game crashes with the error described during the server tick loop.
   Removing or disabling Smoothchunk allows the game to run without crashing, indicating it’s the mod causing the issue.
