Sand Villages With Walls Crash The Server

So something my friends and I have been experiencing on multiple occasions on multiple different worlds (I've deleted old worlds to try to fix the problem thinking it was a corrupted world but it wasn't) is that whenever we go near a sand village (with walls, I don't know which mod actually adds the walls around the village but I think it may be witchery) the entire server just crashes. The first time we noticed this was my friend RedAragon101 went near one and we instantly crashed. We are sure it has to do with the village because this has only ever occurred when someone has gone near one. Tonight (on a brand new world) my friend MidnightHalo went near one and we all crashed. The thing about this is that if MidnightHalo gets on we all instantly crash because she is near the village. I don't know what actually causes the crash but if someone could help me that would be great. I hit the share button for the log but I don't know how to actually get to it for other people. Please help me fix this.

It's my own modpack, I used forge. Most villages are fine but for whatever reason the sand villages that have walls generated around them always crash us.

Okay, my server is 1.7.10 and my mods are:

Advanced Lightsabers

Animal Bikes

Chisel

CoFHLib

Craft Guide

Custom NPCs

Gravity Guns

Hats

Just A Few Fish

More Player Models

MrCrayfish's Furniture Mod

Pam's Harvest Craft

Portal Gun

Techguns

Extra Utilities

Forge Essentials

iChunUtil

Journey Map

Secret Rooms Mod

Witchery

World Edit

My newest mods that I added when we started noticing this problem were Animal Bikes and Just A Few Fish but I don't think either of them are the problem

Not a broken world because we have tried multiple different worlds and I will try to remove hats later I can't mess with the server at this moment but I will get back to this thread after I try it
