1.7.10 Forge 1291 Explosion Crashing Server

[Growlith1223]

Everytime a Creeper, tnt, or even Wither, explodes, the server crashes with:

I have done some research and tried everything but it still seems to persist.

I currently have forge removing entities that error but it's annoying when a wither explodes and does the exact same thing.

The pack is launched with Technic and i am the modpack creator. im not sure if it's a mod i am using orr what but yea. im going to guess it's a mod, just not sure which one.

 

Any help will be appreciated! if there's more information you need, then just say so!

Make a binary search: Take one half of the mods out, test with other half, if it doesn't crash, the mod is in the taken out half.

Do it until you found the mod causing the issue.

Alright i figured out the crash, it was Factorization, i reverted it to an older version and it works perfectly now! thanks for the reply!
