Describe the bug you're experiencing

As description. I attempted to place a Necromancer from Iron's Spells n Spellbooks, via a Mob Yoinker from Utilitix. Result is a crash to desktop, and a crash log starting with Farsight.

Reproducability

Crash occurred in the AllTheMods 9 modpack, version 0.2.57.
Place a Necromancer (from Iron's Spells n Spellbooks) into a Mob Yoinker (from UtilitiX). Rightclick the yoinker onto the ground to cause the crash.

Looks like an issue of utilix and irons spells n spellbooks, trying to cast the clientside chunk manager to ServerChunkCache on render thread seems wrong.

It seems the issue is triggered from utilix loading and creating the mob on client side: https://github.com/MelanX/UtilitiX/blob/6f11ba08ce54b4a1e69c84fb42af1f6d5e2cf088/src/main/java/de/melanx/utilitix/item/ItemMobYoinker.java#L42

Which in turn triggers Irons spells n spellbooks to call its "sync to client" which is expected to run on the serverside not the clientside.
Even without farsight this will crash as you cannot cast to "ServerChunkCache" on the client side
