Launcher Version: 7.2.7 Operating System: 64-bit Operating System Java Version: Java Version 1.7.0_07 from Oracle Corporation Antivirus Program: Description of Problem: I was playing Technic SSP, everything was normal and working properly, and I go into the Nether and get some soul sand and some netherrack. I come back from the Nether at a different location (this always happens, but it is not a problem) and I fly over towards my house. When I get there, most of my house has disappeared as well as the sorting facility. No items from the disappeared chest lay on the floor, and some of the machines I built were also gone without a trace. I logged out and logged back in, but it was still the same. Please help me if you can. Error Messages: Error Log:
