Issue description:

The energy cubes as well as the universal cables stop working when you load into a single player world or a server. The cubes stop outputting power and all of the cables look like they are placed down and not attached to anything. In the picture the cable on the right shows the issue I am describing and the one on top shows that the cable connects when you place it down, but that it will disconnect if you reconnect to the world.

Steps to reproduce:

1. Place down energy cube
2. Connect pipes
3. Re-log into the world

Not really sure what is going on there and I don't recall any bugs like that from when we used to work on 1.12. I am going ahead and closing this as we aren't actively developing 1.12 anymore, but if you provide your latest.log file from when this happens maybe it will have something in it that we can point you towards.
