Client Crash when anyone loads certain areas in a server

Title:

Client Crash when anyone loads certain areas in a server​

Launcher Version:

​

Modpack:

(Lite) Modified Version of the Direwolf20 1.7 Modpack​

Modpack Version:

​

Log Link:

​

Details of the issue:

I use a heavily modified version of the Direwolf 20 1.7 modpack because I cannot run the full one well. I run this pack on a server hosted by creeperhost 24/7, and recently created a new world. If a player loads certain areas of the world, which have been untouched by any players, his/her client will crash. The player will continue to crash each time he/she joins the server. The server, however, never crashes.

Is there a way I can modify my pack or modify the world so that this problem stops happening?

Here is the mod list:

Get rid of Flans mod.

Does Flans mod have any worldgen? (Like dungeons, houses, something)

I REALLY would like to avoid getting rid of Flans mod, but I was hoping if you knew if it had world gen. As far as I know it shouldn't, but assuming that flans mod is solely what causes the crash then it must have some role in world gen.

By the way, I have gone in to MCEdit in the past and deleted all entities, but sadly that did not keep people from crashing.

 

[Moasseman]

I have no idea how Creeperhost run their MC servers, but all I found in the internets about flans mod similar crashes is MCPC+ compatibility issues.

I've never played with flans mod as I'm not really fond of all that pew pew guns thing, so I don't have first-hand knowledge about it.

E: Which mods have you added to the pack that normally don't belong there?

 

[EvasiveParacite]

Which mods have you added to the pack that normally don't belong there?

Flans mod, pams harvest craft, iguana tweaks, apple core, hunger overhaul, spice of life, simply jetpacks, flans mod, mine tweaker recipe maker (but not minetweaker). I have also removed MANY mods from the original pack.

I have tested more, and more, and I noticed the crash only happens in snow taiga biomes. Does this give anyone more of an idea as to how I can fix it? I am about to go into mcedit and change the biome to something else, but I would also like to avoid having this problem in snow biomes discovered in the future. Any ideas?
