I have a backed up save of the very first tutorial from minecraft PS3 edition. Using MCC tool chest, I converted it to PC. I can open the wostrld in PC but all chests are empty and all mobs have disappeared. When I convert it to Wii U it shows up in the list of worlds but when I load it the Wii U crashes. Is there any other converter that actually works properly?
