I having the same issue on the server. The source of the issue is caused by Postbox block.

Crash Log:
java.lang.ClassCastException: class com.minecolonies.core.blocks.huts.BlockPostBox cannot be cast to class com.minecolonies.api.blocks.AbstractBlockHut

⚠️ Summary of the Issue:

Specific problem: The mod tries to treat a Post Box block as a Hut, but they’re incompatible types.

Where it breaks: TileEntityColonyBuilding.loadAdditional() fails due to incorrect casting.

Likely trigger: Joining a world or chunk containing a BlockPostBox tied to a TileEntityColonyBuilding.

💥 What Caused the Disconnect:
The server sent a chunk containing a BlockPostBox, but the client tried to treat it as a AbstractBlockHut, causing a fatal packet error and disconnection.

✅ Solutions:
Remove the PostBox.
