Broken save game - really frustrating!

[JonCage]

I was trying to power up the mining machine but somehow the plug that connects the controls to the wall seems to become corrupted. It's connected and there's no way to disconnect but the desk says it's not powered up :/

I'm posting this in the hope that it can be fixed and to avoid anyone else having to go through the same thing.

I've attached the offending save game..
