Hi, I just came across a very... odd problem in my SSP world. I had built a big house, filled it with loads of good stuff, and decided to go to the Twilight Forest to get some slime balls. I ran around in the Twilight for a while, got some stuff, and decided to head back home. I jumped in the portal, and came out, only to see a battle tower nearby. At first I thought I had been teleported to the wrong place, but that wasn't right, I could see my Nether portal nearby. Then I realised: The chunk had somehow been replaced! Worst of all, it was the chunk my house was on. My house, and everything in it, is gone, and in it's place is a battle tower The only evidence that my house was even there is a bit of fencing which used to be the pen for my Chocobos, and some of the grass from the terraforming I did before building my house.
