I am playing on a server running the Team Rustic 4 modpack. Everything was running smoothly however when I placed an iron farm block my client (on my laptop) crashed. I tried relogging but the same crash kept happening. Strangely when logged in on another computer (my desktop) I was able to put a villager into the farm, which meant I was able to log in with my laptop client again.

This seemed to be working (on my laptop) fine until I just experienced it crashing again. I'm not sure if this time it triggered by me walking into the block/the block updating with an iron golem spawning, causing my client to crash again (find the crash report attached below). Now when I try to log in on my laptop it keeps crashing (Log file below). I was able to log in on my PC again and move, allowing me to relog in on my laptop.

Hopefully you can help as this is quite annoying. I've tried reinstalling the mods and their configs, but nothings helped.

Steps to reproduce the issue

1. Place an iron farm block
2. Experience crash
3. See error

Expected behavior
Able to place Iron farm blocks and have them update without causing client crashes
