Error when attempting to start 1.16.5 fabric server

[gcbrown]

Hi @PTOM76 , I'm getting an issue trying to load Advanced Reborn in a 1.16.5 fabric server. I cannot reproduce the error on a client, only in a server, which is strange.

Minimal steps to reproduce:

1. Download https://fabricmc.net/use/server/, mc version == 1.16.5, fabric loader version == 0.15.*, installer version = any
2. Copy the latest version of Advanced Reborn and its 5 dependencies (MCPitanLib, Architectury, Fabric API, Reborn Core, Tech Reborn) to the mods/ folder in the server
3. Attempt to start the server

Stack trace copied below. The key part seems to be trying to pull in a minecraft object that doesn't exist? Still, I don't understand why it would work fine in a client but not in a server. Hoping these clues can help. Appreciate your work and hoping you have the time to check this out.
