Describe the bug
I'm no good at deciphering crash reports, but it's almost certainly a compatibility thing. The server crashes every time I attempt to launch it, and when the world file was copied to singleplayer it crashed as well. It is in a relatively large modpack, but AcademyCraft was listed as the source so I'm posting it here.

To Reproduce
As I don't know the cause of the error, I don't know how to reproduce it.

Expected behavior
I would expect the server to hopefully not crash when launching a world.

Crash Logs
crash-2019-04-05_11.47.58-server.txt
crash-2019-04-05_11.38.08-server.txt
The first log is for client, the second is for the server. For some reason, the server's report's formatting is awful.

Desktop (please complete the following information):

• OS: Windows 10
• MC Version and Forge version: 14.23.5.2814-1.12.2
• Version 1.1.1

Additional context
The server had been working fine since the mod's release and I've only just started having major issues.

Even if this is a problem on my end, any help fixing it would be greatly appreciated.

The error reads: "java.lang.IllegalArgumentException: Cannot get property PropertyBool{name=connected, clazz=class java.lang.Boolean, values=[true, false]} as it does not exist in BlockStateMachine{block=mekanism:machineblock, properties=[active, facing, recipe, tier, type]}"

I'm not too sure what you did, but were you perhaps connecting a universal cable to an academycraft node?

I'll try to read the crash reports for you a bit. xD

Seems to agrue with: Node Wireless Energy system. 'something' cannot tell if it is connected or not. (as in, using the 'connected' property from a Node.)
