I made a world in the Greenfoot, and it works really well in the greenfoot app, but when i upload it to the website, it says java.util.UnknownFormatConversionException. Anyone knows why?

I have not seen that one before, but if you supply your codes for review, we might be able to figure it out. Start with posting your World subclass.
