So I have this world for survival and when I left it and went back into the world the entire world went back to a certain point except my inventory. This has been happening since Saturday in an older world. I tried it Modded and it happened with just Optifine,World Downloader,Mccapes and rei's minimap. Then I tried it Vanilla and it did the same thing. I am running Minecraft 1.4.2.
