Description

We're playing on a modded server with Peripherals++ (along with ~150 other mods) and I recently started using the advanced turtle teleporter to do some stuff like a global system rebooting and more.

The issue is, sometimes, when a turtle teleports, the server simply crash (see the crash report below). When restarted, the turtle has teleported. It is not systematic but it happened at least 5-6 times when testing the system and every time it was at the precise moment of the teleport, so we're fairly certain that this is the cause. I don't know a certain way to reproduce, but teleporting a turtle repeatedly should do the trick.

Sorry for the bad english, french server here.

Steps to Reproduce

I've tried to reproduce it in a single player world, but it did'nt work. I hope the crash report below will help you to help us anyway.

Expected behavior: The turtle should have teleported without the server shutting down.

Actual behavior: Well... A good'ol shut down right AFTER the teleporting.
