Yes it probably does mean you have completed all the challenges so far (haven't got my kindle with me to check but I think your level would be about right for that).

Since I've been playing I think the new challenges have been coming through about 10 days - 2 weeks after the previous one finishes.

So in between times, yes we improve our inventory and give stuff away, collect tools and artifacts, practice tricky locations and, in my case, start daft threads on here about what Olympic sports the characters would be best at!

Just wait until we get a new challenge and then we will all go into a frenzy :-)
