Summary

When trying to start a Minecraft 1.16.1 server with Refined Relocation 2 it fails with a NoClassDefFoundError, refering to the class net/minecraft/tileentity/IChestLid.

Steps to reproduce

Install Minecraft Server of version 1.16.1 with Forge enabled, and add the RefinedRelocation_1.16.1-8.0.0.jar to the mods/ directory.
Tried with both Forge version 32.0.57, which mod source code seems to be built against, and 32.0.98, latest version.

Expected Results

Server to start properly with no errors, all functionality of the mod enabled in the game.

Actual Results

Server fails to start due to critical error when trying to call the block registration of the mod with Forge.
The error is a NoClassDefFoundError for the class net/minecraft/tileentity/IChestLid.
The Minecraft Client starts fine with the mod installed.

Not a Minecraft Mod Developer, but IChestLid is an interface used by SortingChestTileEntity, and this interface is marked as @OnlyIn(Dist.CLIENT) in the Forge built mapped files. Could this cause the Server issues?
