I found a third player in the world data who could not be found in the Minecraft player database, like a user with a cracked launcher. Do you know something of that?

However, you can download the converted world again from the same adress as before. If it still doesn't work, then it's a bug of one of the other mods. its still not working, and i dont know anything about the other player, ill try removing some mods to see if it works
