Issue description

Hello. My friend and I set up a server for a two-player game on the Techopolis 3 build. We discovered a problem: when you install Machine Extender and connect a logistics transporter to it, the server crashes. Now the server starts, but when you connect to it, it immediately crashes.
Tried to load the world from the server into the client. Launches without problems. But if you teleport to the coordinates of the island where Machine Extender is installed, the client immediately crashes, just like the server.
Maybe there are some ideas how to get around this problem? We want to continue playing :(

I apologize in advance, maybe I explained something incorrectly. I use Google translator.

Steps to reproduce

1. Set Machine Extender
2. Connect Logistical Transporter to it

Minecraft version

We were able to reproduce the problem in a single game. When installing Machine Extender over a logistics transporter from Mekanism, it immediately crashes, and with further entry to the server, it crashes again

it's returning our own item handler when we request the item handler on the connected side. This is caused by the Extenders, though we might be able to work around it...
