Certain Items When Placed Close Server![17.1.0]Custom Modpack!

[JakeT24]

Hey there Technic Forums! My custom modpack, Doge is the real Illuminati, MC Version 1.7.10 has the mods:

-Flans Mod

-Ars Magica 2

-QCraft

-Aether

-MCHelicopter

-ICBM Updated by SpikeViper

-Voltz Engine

-BCMod

-Backpacks

-Thaumcraft

-Explosives++

-TooMuchTnt

-Witchery

-Gilded Games Util

-Not Enough Items

-Code Chicken Core

-Extra Utilities

-Optifine

-Rival Rebels

-Xray

-Archimedes Ships

-Aether

-CoFH Core

-Animation API

-Baubles

-Code Chicken Lib

To better explain my problem, for example, when I place a QCraft Computer, and right click it, the server says stops and says Closed Server. This happens with more than just QCraft, for example when I spawn in a Mecha on Flans mod, or when I placed Tentacles in Thaumcraft or Ars Magica 2. I do not see an error in the console when this happens, all I see is a Server Received Stop Command. Any explanations? Thank you!

I run Cauldron on my server!
