In the normal world I built a medium sized house and to the right of it there was a pond. I built a portal into the Aether in the pond and spent a while in the Aether, around two hours to be exact. After I left the Aether and came back to the normal world. My normal biome turned into a snow biome and my house was just gone. Nothing was left, the glass the walls, the chests, nothing was there. I don't know why and I couldn't find anything else about it. Can anyone help? Thanks.
Maybe the aether teleported you to a different chunk when you left? Is the terrain shape still the same? Is the pond still there? Is the portal still there?
Yeah, the pond and the portal are still there, I'm using Single Player Commands with a wayppoint in my house as "home" and I went to it when I left the Aether and it took me too where it should except the house was gone and replaced with a mountain.
That happened to me when I was using the Flatgrass map. It changed itself it it's former state some how. Everything was gone. That was when I tried to move the map via dropbox and USB, it was fine on the original computer.
Another point for why I dont use mods. Anyway, theres a thread pinned up on support section about fixing broken worlds, beyond that I have no recomendation if youre absolutely sure it is where you entered from.
