Same here, it's a shame too, most of my good stuff was in chests back in my world. Ah well, at least I have my flairon, armor, and money.I am having the same issue. Character transfer works fine, just not worlds.
I hope so. I hate not having all my weaponsUgh, my old xb360 world won't upload to the xb1 either :/ Maybe a bug fix will come later?
