When I left, my base was fine. Nothing wrong. I went to the quarryworld and gathered my quarry up, but when I went back, it all was wrong. My IC2 cables all disconnected from machines and each other. All wiring like itemducts and energy conduits from thermal expansion vanished. All mobs vanished, including my sheep farm and Questing ram. Please fix this, everything is at a halt without this.
To be honest, I thought you already fixed it. When I went back there later it had rolled back, going back to normal but the empty ME drives I put in the system were gone, so I assumed somebody had to have fixed it.
