I just logged on and all of my personal inventory was missing. The progress I made with my house was fine, everything in my chests were fine, but the armor I was wearing and everything on me was lost. 1 diamond sword, iron swords, iron picks, iron axes, 1 shovel, 3 bows, arrows, coal, flint, all kinds of shiz...
What could cause that? Jordie mentioned moving my bed. I did re-arrange my house before I signed off. I moved my bed.
